7. the molar mass of carbon is 12.0 g/mol, of hydrogen is 1.0 g/mol, and of oxygen is 16.0 g/mol.
how would you calculate the molar mass of ethanol (c2h60)?

• 9 mol * 6.02 x 10^23g
• 2 x 12.0g/mol + 1 x 16.0 g/mol
• 9 mol (12.0 g/mol + 1.0 g/mol + 16 g/mol)
• 12.0 g/ mol + 1.0 g/mol + 16 g/mol

2 x 12.0g/mol + 1 x6 +  16.0 g/mol

Explanation:

molecular formula = C₂H₆O           ( carbon= 12g/mol  H= 1g     O=16)

                              =   2 x 12 + 6 x 1 + 16

                             =  46 g    Molecular mass                                

thats a little if u want the answer just look it up on google thats what i do haha : )
