In many chemistry problems, you need to convert grams to moles or moles to grams. The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles. Depending on the input data it can serve either as grams to moles calculator or as moles to gram...
How many moles ofAlare there in a sample that contains15.7grams of aluminum? Number of Moles: The number of moles in a sample can be determined using the following g formula if we know the mass of the substance present: Number of moles =MassofsubstanceMolarmass ...
How many moles are in 100.0 grams of Al2O3? How many moles are in 311 grams of Al2O3? What mass of Al_2(CO_3)_3 contains 4.92 moles of aluminium? How many moles are in 53.0 grams of AlCl3? How many moles are in 12.5 grams of AlCl3?
Ions present: Al3+ and O2–. For electrical neutrality, we need three O2– ions for every two Al3+ ions. (3 × 2−) + (2 × 3+) = 0 So the formula is Al2O3. The formula of a covalent compound is deduced from the number of electrons needed to achieve the stable electronic...
