Scientific models do not describe reality. They are simplifications aid therefore incorrect at some level. So why are models useful?
how much volume is required to make 0.6m of 32.69% h3po4 in 100ml of water where the density of h3po4 is 1.88g/cm3.
22. A 100g of water is mixed to 150g of alcohol (ρ = 0.76 g/cm3). Calculate the resulting density of the solution assuming that it is mixed completely.a. 0.8407g/cm3 b. 0.8379g/cm3 c. 0.8624g/cm3 d. 0.8153g/cm3
To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol 1density 0.785 g>mL2or toluene 1density 0.866 g>mL2. What are the calculated densityand the probable identity of the substance?
Pheromones are compounds secreted by females of manyinsect species to attract mates. Typically, 1.0 × 10−8gof a pheromone is sufficient to reach all targeted maleswithin a radius of 0.50 mi. Calculate the density of thepheromone (in grams per liter) in a cylindrical air spacehaving a radius of 0.50 mi and a height of 40 ft (volumeof a cylinder of radius r and height h is πr2h).
An experiment was performed to look at how density changes when t he ratio of water and ethanol was changed. The following data was obtained: % Mass Ethano1.00 2.50 3.50 4.00 6.00 7.50 9.50 Density, g/mL0.9963 0.9936 0.9918 0.9910 0.9878 0.9855 0.9826 Use Excel or a similar spreadsheet program to plot these six data points and answer the following questions . a.What is the independent variable? b.What is the dependent variable? c.What is the equation of the best-‐fit line? d.What is the value of the coefficient of determination? e. According to the best-‐fit line, what should the density of pure water be (i.e. what is the density when % mass ethanol = 0.00)?
An experiment with a pycnometer resulted in the following data: Mass of Pycnomter = 25.428 g Mass of Pycnometer filled with water = 44.021 grams Mass of Pycnometer filled with liquid X = 41.421 grams a) What is the specific gravity of liquid X? b) If methanol (Specific Gravity = 0.790) was used rather than water in measuring the density of irregular objects, how would that affect the result? Why?
In 2009, a team from Northwestern University and WesternWashington University reported the preparation of a new“spongy” material composed of nickel, molybdenum, andsulfur that excels at removing mercury from water. The densityof this new material is 0.20 g/cm3, and its surface area is1242 m2 per gram of material. (a) Calculate the volume of a10.0-mg sample of this material. (b) Calculate the surface area fora 10.0-mg sample of this material. (c) A 10.0-mL sample of contaminatedwater had 7.748 mg of mercury in it. After treatmentwith 10.0 mg of the new spongy material, 0.001 mg of mercuryremained in the contaminated water. What percentage of themercury was removed from the water? (d) What is the final massof the spongy material after the exposure to mercury?
A mixture of water (D = 1,000 kg/m3) and alcohol (D = 791 kg/m3) has a density of 920kg/m3. Is this mixture mostly water or mostly alcohol? Explain why.
How many cm3 of HF(g) are needed to produce 26.0g of Na3AIF6. The density of HF (g) at 25C is 1.15g/L
The liquid cyanoacetylene has a density of0.817 g/mLat20.0∘C. If a51.9 mLsample of this compound is provided, what is the mass of the liquid at20.0∘Cthat must be provided? (Please type answer no write by hend)
A student working on this lab found the mass of their sample after the first heating to be 30.6057 g. The student heated the sample again for 5 minutes, cooled it, and then found the mass of the sample to be 30.5757 g. Is the sample at constant mass? Show the calculation you used to answer this question.
