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.
