Question

If a compound has a molar mass of 180 g/mol and its empirical formula is CH20, what is its molecular formula?
CH20
C₂H4O2
C6H1206
C12H22011

Answer 1

Answer:

C

Explanation:

The mass of the empirical formula is

C =           12

2H = 2*1 = 2

O = 1 * 16=16

Total =   30

The molecular mass is 180/30 = 6

The means you multiply the empirical formula by 6

(CH2O)_6

C6H12O6

The answer is C

Answer 2

Answer:

C

Explanation:

C6H1206 just look at it it is the best one
