Step 1
- 1 g atom of carbon is equivalent to 1 mole of carbon. - The molar mass of carbon (C) is 12 g/mol. - Therefore, the mass of 1 g atom of C is 12 g. Show more…

Withoutdoing any detailed calculations (but using a periodic table to give atomic weights), rank the following samples in order of increasing number of atoms: $3.0 \times 10^{23}$ molecules of $\mathrm{H}_{2} \mathrm{O}_{2}, 2.0 \mathrm{~mol} \mathrm{CH}_{4}, 32 \mathrm{~g} \mathrm{O}_{2}$
One mole of $\mathrm{CH}_{4}$ contains: (a) $4.0 \mathrm{~g}$ atoms of hydrogen (b) $3.0 \mathrm{~g}$ atom of carbon (c) $6.02 \times 10^{23}$ atoms of hydrogen (d) $1.81 \times 10^{23}$ molecules of $\mathrm{CH}_{4}$
