Question

How many moles are in 25.2 g of C6H10S?

Answer 1

0.221 moles

Step-by-step explanation:

• The relationship between molar mass, number of moles and mass of a compound is given by;

Number of moles = Mass ÷ Molar mass

• Therefore, when given the mass and the formula of the compound we can determine the number of moles.

In this case;

Mass of C6H10S = 25.2 g

Molar mass of C6H10S = 114.21 g/mol

Therefore;

Number of moles of C6H10S = 25.2 g ÷ 114.21 g/mol

= 0.221 moles

Hence, the number of moles in 25.2 g of C6H10S is 0.221 moles
