Question

What is the formula mass (molar mass) of sucrose (C12H22O11), table sugar? Question 11 options: 130 g/mol 29 g/mol 386 g/mol 342 g/mol Save

Im not sure if it would be 386 g/mol or 342 g/mol

Answer 1

Answer: The molar mass of sucrose is 342 g/mol

Step-by-step explanation:

Molar mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

The molecular formula of sucrose is
`C_(12)H_(22)O_(11)`

We know that:

Atomic mass of carbon = 12 g/mol

Atomic mass of hydrogen = 1 g/mol

Atomic mass of oxygen = 16 g/mol

Molar mass of sucrose =
`(12* 12)+(22* 1)+(11* 16)]=342g/mol`

Hence, the molar mass of sucrose is 342 g/mol
