Question

use the data in the table to answer the following questions. how many grams of compound were formed?
aluminum and liquid bromine reaction

	before reaction	after reaction
liquid bromine	100.0 g	8.5 g
compound	0.0 g

100.0 g
101.8 g
10.3 g
91.5 g

Explanation:

Step1: Calculate used liquid bromine mass

Mass of used liquid bromine = Initial mass - Remaining mass = $100.0 - 8.5=91.5$ g

Step2: Apply law of conservation of mass

According to the law of conservation of mass, mass of compound formed = Mass of aluminum used+Mass of used liquid bromine. Mass of aluminum used is 10.3 g and mass of used liquid bromine is 91.5 g. So mass of compound formed = $10.3 + 91.5=101.8$ g

Answer:

101.8 g
