DrBob222, do you know how to do this?
The density of H2O=1g/mL, solve for mass.
mass=density*volume=(1g/mL)*(500mL)=500g or 0.500 kg
m=moles of solute/kg of solvent, solve for moles
(0.100 mol/kg)*(0.500 kg)= moles of CaCl2
moles of CaCl2*(111.0g/mole)= mass of CaCl2
****I'm not Dr. Bob222, but I think this is correct.
I'll buy all of that. Something like 5.55 g if I punched in the right numbers
