To find the molar mass of Aluminum Oxide (Al2O3), you need to add the molar masses of the individual elements. The molar mass of aluminum (Al) is approximately 27 g/mol, and the molar mass of oxygen (O) is approximately 16 g/mol. Therefore, the molar mass of Al2O3 is (227) + (316) = 102 g/mol.

The molar mass of SO3 is 80.06 g/mol. Oxygen makes up three of these four atoms, so the oxygen's molecular weight in SO3 is 48 g/mol (3 x 16). Therefore, the percent by weight of oxygen in SO3 is (48 g/mol / 80.06 g/mol) x 100% = 59.97%.
360/7.5 = 48 grams per cm3.Note: The math is valid, but that number is more than double the density of theheaviest element on earth, and four times the density of lead.
48 g 19 mg is equal to 48.019 g.
No not yet... but right now they have the 1 g, 2 g, 3 g, and 4 g
The molar mass of Fe2O3 is 159.7 g/mol. The molar mass of O in Fe2O3 is 48 g/mol. Therefore, the percent by mass of oxygen in Fe2O3 is (48 g/mol / 159.7 g/mol) * 100 = 30%.
24 - 4 = 20
