Question

What mass of water will react with 15.98g of bromine

Answer 1

Answer:

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
