Question

2H2+O2→2H2O.2g H2 and 1g O2 react to form H2O

Answer 1

hey mate, here is ur answer

Molar mass H2 = 2 g/mol

Moles H2 = 2 g / 2 g/mol = 1

Molar mass O2 = 32 g/mol

Moles O2 = 1 / 32 = 0.03125

2 H2 + O2 >> 2 H2O

the ratio between H2 and O2 is 32 : 1 so we get 1 mole of water => 18 g

hope IT will help u
