Question

Valine is an amino acid with the formula C5H11NO2. Determine the number of moles of carbon in 99.82 g of valine.

Answer 1

Moles of carbon in 99.82 g valine

$99.82 g C_{5}H_{11}NO_{2}$×$\frac{1 mol C_{5}H_{11}NO_{2}}{117.15 gC_{5}H_{11}NO_{2}}$×$\frac{5 mol C}{1 mol C_{5}H_{11}NO_{2}}$

= 4.26 mol C
