Question

Calculate the percentage composition of chloroform chcl3 a substance once used as anesthetic

Answer 1

$\underline \green{answer :}$

2. Peroxyacylnitrate ( PAN ) is one of the compound of smog. It is a compound of C, H, N , and O. Determine the % composition of oxygen and the empirical formula for the following percent composition by mass 19.8% C, 2.50% H, 11.6% N. What is its molecular formula given that its molar mass is about 120 g.

Answer 2

1.007947 / 119.3783 = 0.008443302 = 0.8443302% H

Cl3 = 106.3596 g/mol

106.3596 / 119.3783 = 0.8909458 = 89.09458% Cl
