Question

Refer to the periodic table to find the correct molar mass for each element and compound.

Cl
CH4
C2H6
O2
O
S

Answer 1

Answer: 35.4 g/mol ; 16g/mol ; 30.07g/mol ; 32g/mol ; 16g/mol ; 32g/mol

Explanation: For CH4 : C=12g/mol ; H = 2g/mol

Hence CH4 is 16g/mol

For C2H6 : C = 12g/mol ; H = 2g/mol

Hence C2H6 is 30.07g/mol

For O2 : O = 16g/mol

Hence for O2 is 32g/mol
