Answer: 708.2 grams
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Given : 38 g of is dissolved in 100 g of solution.
Density of solution = 1.285 g/ml
Volume of solution =
Thus if 77.8 ml of contains = 38 g of
1.45L= 1450 ml of contains =
of
Therefore, the mass of the sulfuric acid in a car battery is 708.2 g
