Answer:

Percentage composition H in HBr = 1.236%

Percentage composition Br in HBr = 98.764%

Explanation:

H = 1g/mol

Br = 79.904g/mol

HBr = Molar Mass 80.904 g/mol

Percentage composition of X = (X / Molar Mass) x 100

H = (1/80.904) x 100            = 1.236%

Br = (79.904/80.904) x 100 = 98.764%
