Question

The empirical formula of CBr2 has a molar mass of 515.46 g/mol. What is the molecular formula of this

compound

Answer 1

C3Br6

Step-by-step explanation:

C= (1 X 12.011) = 12.011

Br= (2 X 79.904)= 159.808

159.808+12.011 = 171.819

515.46 divided by 171.819 = 3.00

so you mulitpy CBr2 by 3 which gives you C3Br6
