Question

There are 3 astronauts, and each produce 500g of CO2 every day. This means they will produce 3000g of CO2 in 2 days (3 x 500g x 2 = 3000g). How many moles of CO2 is that? (round to the nearest tenth) *

Answer 1

Find the molecular mass of CO2 (atomic mass of C + 2 X atomic mass of O). Call this x

Then number of moles = 3000 / x
