An aqueous solution of NaCl has a mole fraction of 0.21. What is the mass of NaCl dissolved in 100.0 mL of solution? [closed]
Work
mole fraction of NaCl = 0.21/0.21+0.79
If there is 1 mol of total solution, there will be 0.21 mol NaCl and 0.79 mol H2O
0.21 mol NaCl = 12.27 g
0.79 mol H2O = 14.23 g
this would yield a ...

CuCl2 dissolved in water
We dissolve $10\ \mathrm{g}$ of $\ce{CuCl2}$ in $0.1\ \mathrm{L}$ of water.
Given that:
$M(\ce{Cl})=35.5\ \mathrm{g/mol}$
$M(\ce{Cu})=63.5\ \mathrm{g/mol}$
How can one calculate the molar ...
