Question

How many moles of H2 would be formed from 2.26 mol of HCI?

Mg + _HCI → _MgCl2 + H2

Answer 1

2.6 moles of HCl will produce moles of H2 =
`1.3`

Step-by-step explanation:

Mass of HCl is 36.458 g/mol

Mass of Hydrogen is 1.00794 g/mol

The balanced equation here is

Mg + 2_HCI → _MgCl2 + H2'

2 moles of HCl produces one mole of H2

One mole of HCl will produce moles of H2 =
`(1)/(2)`

2.6 moles of HCl will produce moles of H2 =
`(1)/(2) * 2.6 = 1.3`
