How many atoms in aluminum
WebFeb 5, 2024 · Answer:54.0 g of aluminum Molar mass of aluminum (Al) is 26.9815386 g/mol. So 1 mole of aluminum has a mass of 26.9815386 grams. Thus, the number of moles in 54.0 g sample of Al is 54.0g/26.9815386g/mol = 2.00137 moles. Explanation: WebOct 23, 2024 · first convert grams into moles. mass of Al given in problem in grams * ( 1 mol / atomic mass of Al in grams) 44.8g * (1 mol / 26.982g) (this causes the unit of grams to cancel leaving units of moles) = 1.66 mol. Use avagadros number to convert into atoms of Al. Avagadros number (this number is a constant) = 6.022E23 or 6.022*10^23.
