To find the atomic mass of chlorine, the atomic mass of each isotope is multiplied by the relative abundance (the percent abundance in decimal form) and then the individual masses are added together. The atomic mass of chlorine is 35.45 amu.
D.) There must be an equal number of atoms of each element on both sides of the equation
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
