Molarity= mol solute/ L soln
d=m/V (where m=mass and V=volume).
V=m/d ( rearranged)
V=690.7 g/1.329 g/cm^3
V=519.714 cm^3
where 1 cm^3= 1 mL so,
V=519.714 mL or 0.519714 L
690.7 g H2SO4 [1 mol H2SO4 / 98.086 g H2SO4] = 7.0418 mol H2SO4
Molarity= mol solute/ L soln
Molarity= 7.0418 mol / 0.519714 L
Molarity= 13.549 M
Hope this helped, if it did, please choose best answer. Good luck!
