Solve for M = molarity. M = moles/L soln
Use density to determine the volume of 100 g of the soln, then calculate moles. Finally, moles = grams/molar mass.You know g and moles, solve for molar mass.
Commercial hydrazine is sold as a 64% solution. Using that as your starting material, how would you prepare a 5% solution of hydrazine? well if it is sold as 64% solution would that mean that it has 64g of hydrazine per 100ml of
What mass of CsBr must be added to .500L of water to produce .4molality solution? What are mole fraction and mass percent? Here is my work and below I will post a question about it: 1 mol CsBr = 212.81g density of water = 1g/mL
An ethanol-water solution is prepared by dissolving 10.00 ml ethanol C2H5OH (density=0.789g/ml) in sufficient water to produce 100.00 ml of solution with a density of 0.982g/ml. What is the concentration of ethanol in this
Q4) Suppose you prepare 950 mL of a solution by dissolving 100 grams of NaCl in 900 mL of water. Assuming the density of pure water to be 1 g/mL, answer the following questions with regards to this solution: a) What is the mass
Thimerosal is an organic compound (gram molecular mass = 404.8 g/mol) used to inhibit bacterial growth. A .100%solution of thimerosal is sometimes used as an antiseptic. Assume that this solution has a density of 1.00 g/mL. A. how
I have a solution made up of 100 ml of distilled water and 2.0g of NaOH. I need to determine the total volumeof the solution in order to the calculate the mass of the reaction mixture. How do I do this? We are to assume the
I'm having a lot of trouble with a simple problem. I have a 3.0% by man solution of H2O2 in H2O. The density of thr solution is 1.0 g/mL. I need to find the molarity. How do I do this? So far I have: 3.0g H2O2 x 1 mol/34.02 g=
An excess of zinc metal is added to 50.0 mL of a 0.100 M AgNO3 solution in a constant-pressure calorimeter. Assuming that the density of the solution is the same as for water, calculate the mass of the solution.
A 100.0 mL sample of 0.300 M Ca(OH)2 is mixed with 100.0 mL of 0.700 M H3PO4 in a coffee cup calorimeter.If both solutions were initially at 35.0 °C and the resulting solution had a temperature that was recorded at 39. 7°C,
