Answer:

6.67moles

Step-by-step explanation:

Rubbing alcohol has a formula as C3H8O.

Molar Mass of C3H8O = (3x12) + (8x1) + 16 = 36 + 8 + 16 = 60g/mol

From the question:

Mass of rubbing alcohol (C3H8O) = 400g

Number of mole = mass /molar Mass

Number of mole = 400/60

Number of mole = 6.67moles
