Feedback 9SeeHint The ratio of hydrogen atoms (H) to carbon atoms (C) in the Sun's atmosphere is approximately 2,400 to 1. It is reasonable to assume this also applies to molecular clouds. Radio observations show that a molecular cloud contains 100 Mo of carbon monoxide (CO) in a giant molecular cloud How much carbon is contained in the cloud? Carbon represents 3/7 of the mass of a CO molecule. Mo 943 How much hydrogen is contained in the cloud? Remember...
