Question

How many moles are in 18.3 g of CO2?

Answer 1

0.416moles

Step-by-step explanation:

Using the formula;

number of moles = mass ÷ molar mass

Molar mass of CO2 = 12 + 16(2)

= 12 + 32

= 44g/mol

According to the information in this question, there are 18.3g of CO2

number of moles (n) = 18.3/44

= 0.4159

= 0.416moles of CO2
