Question

calculate the number of moles in 4.4 gram of carbon dioxide.​

Answer 1

• The formula for calculating the number of molecules is.
• No. of molecules = No. of moles x Avogadro's number. First, find the no of moles of CO2: No. of moles = mass of substance/molar mass of a substance. = 4.4 g / 44 gmol-1. = o.1 moles. ...
• = 6.023 x 10^22. So , 4.4 g of CO2 has 6.023 x 10^22 molecules.
