Question

if 2.61g of CuNO3 is dissolved in water to make a 0.480M solution, what is the volume of the solution?

Answer 1

Moles of $CuNO_3=\frac{mass}{molar\ mass}=\frac{2.61}{125.55}=0.02078\ mole$

Molarity = $\frac{moles}{volume(in\ l)}=0.480=\frac{0.02078}{volume(in\ l)}$

volume = $\frac{0.02078}{0.480}=0.0433\ l$

volume$=43.3\ ml$
