Question

Based on the given equation write down the answers.
$2H_2+O_2\to H_{2}O$
How many OXygen and HYdrogen is needed for making $1800g$ of water vapor?

Answer 1

$36g$ of water vapour can be made using $4g$ hydrogen.

The amount of hydrogen required to make $1g$ water vapour $=4/36$

The amount of hydrogen required to produce $1800g$ watervapouur $=4/26\times 1800=200g$

Mass of oxygen $=1800-200=1600g$c
