A compound with the empirical formula ch2 has a molar mass of 70 g/mol. what is the molecular formula for this compound?
Rainbow [258]

The empirical formula, <span>C<span>H2</span></span>, has a relative molecular mass of

<span>1×<span>(12.01)</span>+2×<span>(1.01)</span>=14.04</span>

This means that the empirical formula must be multiplied by a factor to bring up its molecular weight to 70. This factor can be calculated as the ratio of the relative masses of the molecular and empirical formulas

<span><span>7014.04</span>=4.98≈5</span>

Remember that subscripts in molecular formulas must be in whole numbers, hence the rounding-off. Finally, the molecular formula is

<span><span>C<span>1×5</span></span><span>H<span>2×5</span></span>=<span>C5</span><span>H<span>10</span></span></span>
