Mass of solvent(#CH_4O_2#)=300 g

Mass of solute (#HNO_3#)=7.5 g

Mass of solution (w)=307.5g

Density of solution (d) =#0.95" g/"mL#

Volume of solution (V) =#w/d=(307.5g)/(0.95" g/"mL)#
#~~323.7mL=0.3237L#

Number of moles of #HNO_3# in 7.5g is #=(7.5g)/(63" g/"mol)#

#~~0.12mol#

So strength of #HNO_3#

#=0.12/0.3237M~~0.37M#
