Question

The density of sucrose (C12H22O11) is 1.587 g/cm cubed. What volume will 1.5 moles of this substance fill?

Answer 1

C12H22O11 molar mass 12*12+22=16*11=342g

volume 1.5*342/1.587=323.25 cm^3

Answer 2

well, you first meed to get the mass of sucrose for 1 mole: add the atomic masses for 12 carbons, 22 hydrogens, and 11 oxygens. Then, multiply by 1.5, and look in the textbook cause i'm stumped. I can't remember my old chem classes.

Answer 3

Get the molecular weight of sucrose.

Multiply it by the 1.5 mol to cancel out the moles from the MW to get the mass of sucrose.

Take the mass of sucrose and divide it by 1.587 g/cm^3.

Now you have a  value in cm^3.  1cm^3 = 1 mL.

YOU GOT THE VOLUME!!!
