Question

A student measures 14.0 g of copper (II) nitrate and adds it to a 250 mL volumetric flask. What should be the recorded molarity?

Answer 1

`"Concentration "="Moles"/"Volume of solution"` `=0.3*mol*L^-1`

Explanation:

`"Concentration "=`

`(14.0*g)/(187.56*g*mol^-1)xx1/(0.250*L)~=0.30*mol*L^-1` with respect to copper nitrate.
