Chemistry Question Help

Could someone help me with this question? Thanks

A moth of mass 1g consumes 50cm^3 of oxygen (at STP) per hour of flight. If sugar, C6H12O6, supplies energy for the flight, what is the minimum mass of sugar the moth must gather hourly from plants?

Method: Calculate n(O2) (using general gas equation, if you want to) and then use ratios to find n(C6H12O6) using the equation for cellular respiration. Then calculate mass (n=m/M).
