Question #67709

Answer 1

The mass of the compound is irrelevant in this problem, probably meant to confuse us.

`6.78g * (CO_2)/(44.0g) approx 0.154mol`
`1.94g * (H_2O)/(18.0g) * (2H)/(H_2O) approx 0.216mol`
`0.432g * (N_2)/(28.0g) * (2N)/(N_2) approx 0.0309mol`

Divide every number that's larger than the smallest amount of moles and we get...

`C_5H_7N`
