Answer :
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 [tex]H_2SO_4[/tex] is dissolved in 100 g of solution.
Density of solution = 1.285 g/ml
Volume of solution = [tex]\frac{mass}{density}=\frac{100g}{1.285g/ml}=77.8ml[/tex]
Thus if 77.8 ml of [tex]H_2SO_4[/tex] contains = 38 g of [tex]H_2SO_4[/tex]
1.45L= 1450 ml of [tex]H_2SO_4[/tex] contains = [tex]\frac{38}{77.8}\times 1450=708.2 g[/tex] of [tex]H_2SO_4[/tex]
Therefore, the mass of the sulfuric acid in a car battery is 708.2 g
