What mass of water will react with 15.98g of bromine

The answer to your question is  1.79 g of H₂O

Explanation:

Data

mass of water = ?

mass of bromine = Br = 15.98 g

Process

1.- Write the balanced chemical reaction

             H₂O  +  Br₂   ⇒   HBr  +  HBrO

2.- Calculate the molar mass of H₂O and Br₂

H₂O = 2 + 16 = 18 g

Br₂ = 2 x 80 = 160

3.- Use proportions to find the mass of water

                    18 g of H₂O 160 g of Br₂

                      x                 15.98 g of Br₂

                         x = (15.98 x 18) / 160

                         x = 287.64/160

                           x = 1.79 g of H₂O

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
