Question 6 (17 points)
Find the number of moles in 508 g of ethanol (C₂H6O).

Answer 1

11.043 moles

Step-by-step explanation:

• In order to calculate the moles, we first need to find the molar mass of the compound.

Therefore:

Mr of C
`_(2) }`H
`_(6)`O = (12 x 2) + (1 x 6) + 16

= 46 g

• Now to calculate the moles we use the formula : given mass/molar mass

Therefore we get: 508/46 = 11.043 moles
