Hydrogen gas is a molecule.
Thus H2. (H mass no. =1)
RMM=1×2=2
RMM=GMM
GMM=2g
Thus, 1 mole of h2 weighs 2g
Now,
1 mole:2g
and x moles weigh 18g
Thus,
1mole:2g::xmoles:18g
Therefore,
2x=18
x=9
Thus answer is 9 moles.
Thus H2. (H mass no. =1)
RMM=1×2=2
RMM=GMM
GMM=2g
Thus, 1 mole of h2 weighs 2g
Now,
1 mole:2g
and x moles weigh 18g
Thus,
1mole:2g::xmoles:18g
Therefore,
2x=18
x=9
Thus answer is 9 moles.
