(a)

To determine
The number of moles in the sample.

Explanation

Given Info: Mass of formaldehyde (m) is 275 g. The molar mass of formaldehyde ( MF ) is 30 g/mol.

Formula to calculate the number of moles in the sample is,

n=mMF

Substitute 275 g for m and 30 g/mol for MF to get n

(b)

To determine
