We’re being asked to determine the mass of sulfuric acid in a 1 gallon of battery acid if the solution has a density of 1.31 g/mL and 38.2% sulfuric acid by mass.

Recall that density is given by:

$\overline{){\mathbf{density}}{\mathbf{}}{\mathbf{\left(}}{\mathbf{d}}{\mathbf{\right)}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}}{\mathbf{volume}\mathbf{}}}$

*We will do the following steps to solve the problem:*

*Step 1: Convert the volume of the solution from gallon to mL*

*Step 2: Calculate the mass of the solution using density*

*Step 3: Calculate the mass of sulfuric acid in the battery acid solution*

Automobile batteries contain sulfuric acid, which is commonly referred to as "battery acid".

Calculate the number of grams of sulfuric acid in 1 gallon of battery acid if the solution has a density of 1.31 g/mL and is 38.2 % sulfuric acid by mass.
