How many moles are in 15 grams of carbon dioxide?

There are 0.34 moles of CO2 in 15 grams of CO2

Explanation:

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 mole CO2.

Molar mass of CO2 = Molar mass of Carbon + Molar mass of Oxygen multiplied by 2

Molar mass of carbon = 12 g/mol

Molar mass of oxygen= 16g/mol

Molar mass of CO2= 12g/mol + (16g/mol)2

= 12g/mol +32g/mol= 44g/mol

In other words, we can say that 1 mole of CO2 has a mass of 44gram

Number of moles of CO2 = mass of CO2 / molar mass of CO2

Mass of CO2= 15g/mol

Number of moles of CO2= 15gmol-1 / 44gmol-1

= 0.3409 moles

Hence, there are 0.34moles of CO2 present in 15 grams of CO2.
