I need help asap! (question 4)

A 0.5M aqueous solution of sulfuric acid flows into a process unit at a rate of 1.25 m3/min. The specific gravity of the solution is 1.03. Calculate: a. The mass concentration (H2SO4) of H2SO4 in kg/m3 b. The mass flow rate (mH2SO4) of H2SO4 in kg/s c. The mass fraction (wH2SO) of H2SO4 Note: the specific gravity of a substance is the ratio of that substance's density () to the density (ref) of a reference substance at a specific condition (this is normally water): SG=ref
