Question

What mass of water (H2O)will be collected if 20.0 grams of oxygen gas(H2) are consumed
2H2+O2-->2H2O

Answer 1

Explanation:

no.mole of H2= mass/RAM

=20/2(2)

=5mol

no.mole of H20=mass/RAM

=5molx2(2+16)mol/g

=180g

Answer 2

The mass of water should be 180g.

• The calculation is as follows:

$no\ of\ mole\ of\ H2 = mass\div RAM$

$=20\div 2(2)$

=5mol

And, the mass of water should be

$=5mol\times 2(2+16)mol/g$

=180g
