Question

Temperature formula of a compound is ch2o and its molecular weight is 120 the molecular formula of the compound is

Answer 1

Answer:

Let's start by finding the empirical formula mass of this compound:

CH2O= C + (2)H + O = 12.0 + 2(1.0) + 16.0= 30 grams per mole

120÷30=4

Since the molar mass of the compound is four times the empirical formula mass, the molecular formula is four times the empirical formula:

4(CH2O)=C4H8O2
