find the concentration in moles per liter( mol L^-1) and in grams per liter( gL^-1) of the original undiluted cerium sulfate solution? H2O2 + 2 H^(1+) +2Ce^(2+) ====> 2H2O + 2Ce^(3+) A solution of cerium (II) sulfate was analysed by the following steps: I) 50.00 mL of the solution was...

A sample of 10.00g of a solid unknown was dissolved in 25.00g of water. Pure water freezes at 0.0 degrees C and the solution freezes at -5.58oC How can I find the molal concentration of the solution? And the molar mass of the solid?

What is the molarity of a solution that contains 17 g of NH3 in 0.50 L of solution

The calorimeter is prepared with 44.96 g of water, both at 22.6 Celsius. 2.42 g of salt are dissolved in the water ( note the total solution mass) and the temperature falls to 19.9 Celsius . Calculate the heat of the solution for the salt. If the salt is potassium chloride, calculate...

mass of 50 mL beaker + Nacl = 33.6571g mass of "empty" 50 mL beaker/g = 32.0753g mass of NaCl used/g = 1.5818g Final volume of solution /L= 250mL
