WebCalculate the number of moles in each of the following masses: a. 64.1 g of aluminum 02:38 How many moles of Al2O3 can be made with 12.5 grams of Al 00:37 How many moles of aluminum do 3.7 * 1024 aluminum atoms represent? 01:46 How many moles of aluminum do 3.7 * 1024 aluminum atoms represent? Transcript WebThe molar mass of aluminum is 26.98 g/mol. Therefore, the number of moles of aluminum in 64.1 g is: moles = 64.1 g / 26.98 g/mol. moles = 2.37 moles. 2. To calculate the number of moles of Fe2O3 in a 5.00 g sample, you will need to use the formula: moles = mass / molar mass. The molar mass of Fe2O3 is 159.69 g/mol. WebTo calculate the number of moles of aluminum in a sample, divide the mass of the aluminum by the Avogadro's number (6.022 x 1023). In this case, 2.98 g/mol = 6.022 x 1023/mol. Therefore, there are 29.4 moles of aluminum in the sample. Best Match Video Recommendation: Solved by verified expert daniel crocker realty
