Automobile batteries are filled with an aqueous solution of sulfuric acid. what is the mass of the acid (in grams) in 800. ml of the battery acid solution if the density of the solution is 1.285 and the solution is 38.08% sulfuric acid by mass?

391.462 g

Explanation:

First, let's calculate the total mass of the solution by the definition of density (d)

d = m/V, where m is the mass in gram and V the volume in mL. So for the given solution

1.285 = m/800

m = 1028 g

The mass of sulfuric acid will be:

0.3808x1028 = 391.462 g
