A suspension was prepared by mixing spherical gum grains with a density of 1.206 gcm-3 and a radius of 0.212 μm and water with a density of 0.999 gcm-3 at 15˚C. Since the number of particles determined microscopically at 5 μm and 35 μm heights from the base is 100 and 47, respectively, in the same time, calculate Avagadro's constant (g= 9.8 m s-2, μm= 10-6 m)

Analytical chemistry is a particular field within the broader spectrum of the chemical sciences, in which many times the focus of analytical experiments is to develop new methods to analyze compounds, either structurally or by determining concentrations of compounds. One of the processes analytical chemists use to determine the exact concentration of a working solution is called standardization. In your own words, describe the differences between a primary, secondary, and tertiary standard, and describe the underlying concept behind the standardization process. Why is it done?
Assume that a solute has a D* of 2.03 x 10-9 m2 / Sec and that w is equal to 0.5. If landfill leachate with a chloride concentration is next to a clay liner that is 2 m thick and the concentration of chloride is 2315 mg/L, what would be the chloride concentration at the outside of the liner after 25 years of diffusion. ? ignore any effects of advection. Defining a "release" from the landfill as a concentration exceeding 1 mg/l, how long will it take for a release to occur by diffusion alone? Provide answer in years to the nearest tenth. Eg: 10.3
The atomic hydrogen exists in space at an estimated concentration of one particle per cubic meter. If the collision diameter is 2.5 ×10^(–10) meter and the temperature is 2.7 Kelvin, how many kilometers away will the next potential collision be? Express the answer in three significant figures.
When drinking water is disinfected with chlorine, an undesired byproduct, chloroform (CHCl3), may form. Suppose a 70-kg person drinks 2 L of water every day for 70 years with a chloroform concentration of 0.08 mg/L (the drinking water standard).

You take a representative soil sample and determine the following data: Exchangeable cation cmolc/kg of soil Ca2+ 2.7 Mg2+ 1.0 K+ 0.1 H+ 1.0 Al3+ 2.8 Na+ 0.1 1) What is the CEC (cmolc/kg ) of this soil?
1. The great, great grandparents of one of your classmates sold their factory to thegovernment 104 years ago for $150,000. If these proceeds had been invested at 6%,how much would this legacy be worth today? Assume annual compounding. 2. A friend who owns a perpetuity that promises to pay $1,000 at the end of each year,forever, comes to you and offers to sell you all of the payments to be received after the25th year for a price of $1,000. At an interest rate of 10%, should you pay the $1,000today to receive payment numbers 26 and onwards? What does this suggest to youabout the value of perpetual payments? 3. Your aunt, in her will, left you the sum of $5,000 a year forever with payments startingimmediately. However, the news is better. She has specified that the amount shouldgrow at 5% per year to maintain purchasing power. Given an interest rate of 12%, whatis the PV of the inheritance?
How would each of the following errors affect the determination of the molar mass of the unknown (Increase/Decrease/No effect)? a. Thermometer reads 2.0o higher than the true temperature. b. Some of the t-butanol was unknowingly spilled after it had been weighed but before the solute was added. 3. A student accidentally added acetylsalicylic acid (MW = 180.157 g/mol) rather than salicylic acid (MW = 138.121 g/mol), if no other mistakes were made, how would this error affect the determined molal freezing point depression constant for t-butyl alcohol (Kf)? 4. Based on the Tf and Kf you determined for t-butyl alcohol, predict the freezing point of a t-butyl alcohol solution containing 0.530 m NaCl. Assume 1.9 is the van’t Hoff factor for NaCl in t-butyl alcohol. Show your work.
On the occasion of World Health Day, Dr. Satpal organized a ‘health camp’ for the poor farmers living in a nearby village. After check-up, he was shocked to see that most of the farmers suffered from cancer due to regular exposure to pesticides and many were diabetic. They distributed free medicines to them. Dr. Satpal immediately reported the matter to the National Human Rights Commission (NHRC). On the suggestions of NHRC, the government decided to provide medical care, financial assistance, setting up of superspeciality hospitals for treatment and prevention of the deadly disease in the affected villages all over India. (i) Write the values shown by (a) Dr. Satpal (b) NHRC. (ii) What type of analgesics are chiefly used for the relief of pain of terminal cancer? (iii) Give an example of artificial sweetener that could have been recommended to diabetic patients.

It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent. The formula is: mass % of component= (mass of component / total mass) x 100% 1) Reproduce the following table, and use the data to determine the mass % of fat in the chips for each trial. 2) Show one example calculation.
