Calculate the mass of 4.275x1021 molecules of chloroform (CHCl3).
(when I take the given molecules and divide avagrados 6.022x10^23 than multiply by molar mass of 119.38g/mol I get a number way off...what am i doing wrong?).
Homework Answers
CHCl3 = 119.38 g/mol
6.023 x 1023 molecules = 119.38 g
4.275 x 1021 molecules = (4.275x1021 x 119.38) / (6.023 x 1023)= 0.85 g

A polymer of large molar mass is dissolved in the organic solvent chloroform (CHCl3) at 25 °C, and the resulting solution rises to a final height of 7.99 cm above the level of the pure solvent, as solvent molecules pass through a semipermeable membrane into the solution. If the solution contains 3.97 g polymer per liter, calculate the molar mass of the polymer. Take the density of the solution to be 1.48 g cm-3.

Calculate the molar mass of calcium nitrate. Calculate the molar mass of calcium nitrate. 164.10 g/mol 132.10 g/mol 102.09 g/mol 136.03 g/mol none of the above I typically understand how to calculate the molar mass but not when it is a compound. I originally got 102.09 but it was marked wrong on my homework and I do not know how to get to the correct answer.
