Record macroscopic observations of the bag and the crash test dummy as well as microscopic observations of the particles within the steering mechanism and the inflated/inflating airbag.Scientist 1 analyzed the compounds first then gave it to scientist 2 for the next test. Scientist 2 needs to know the molar mass of the active compound. The concentration of the solution they created is twenty percentw/w from the solid active compound and it has a density of 1.40 grams per millilitre. Ten microliters were taken from this solution and mixed with one hundred ninety microliters of reagent and water. After analyzation, it showed that the compound's concentration is Five times ten raised to negative four M i. Find the concentration of the twenty percentw/w solution. The concentration must be in the form of molarityii. Explain the reason why the concentration of the solution was expressed as %w/w initially?iii.

- Can you work our KSP for me? thanks Liquid Amount - How many grams of each of the following substances will dissolve in 4.70×102 mL of cold water? Substance - The solubility is 0.123 g/100 mL at 20 oC. ( Ce(IO3)4 )1) Commercial fuming Sulphuric acid (Oleum-H2S2O6) is 99.9% solution. Please convert it into molarity.2) Find out the Volume (dm3) of product (gas) at RTP when 0.58 M, 150 mL NaOH (aq.) reacts with 350 mL, 0.25 NH4Cl.How would I solve Problem 4? I have the excel graph as provided. Need to get the %Mn I have some small idea but think is wrong... would be... %Mn = 500mL * 1molMn/ g MnO4 * 1molMn/1molMnO4- * gMn/1molMn * 100%/SampleMassg

- The % purity of a powdered crude sample of Na^2CO^3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr. Write the balanced chemical equation of the reaction in your solutions sheet. What is the sum of all the coefficients of the balanced chemical equation?
