Explanation:

no.mole of H2= mass/RAM

=20/2(2)

=5mol

no.mole of H20=mass/RAM

=5molx2(2+16)mol/g

=180g

The mass of water should be 180g.

  • The calculation is as follows:

[tex]no\ of\ mole\ of\ H2 = mass\div RAM[/tex]

[tex]=20\div 2(2)[/tex]

=5mol

And, the mass of water should be

[tex]=5mol\times 2(2+16)mol/g[/tex]

=180g
