Al + O2 = Al2O3 is a Synthesis reaction where four moles of Aluminium [Al] and three moles of Dioxygen [O 2] combine to form two moles of Aluminum Oxide [Al 2 O 3] Aluminum powder sprinkled on a flame + (temperature) → Aluminium lighted white solid form. Aluminium burns in oxygen to form Al2O3.
To convert between moles and grams, multiply moles by the molar mass to get grams, or divide grams by the molar mass to get moles. For example, lets say we have 100g of MgCl2 and want to convert it to the number of moles: 100/95.211 = 1.05 moles.
This mole calculator helps to determine the number of moles, mass, or molecular weight of a substance. Convert grams to moles effortlessly with this tool.
Convert grams to moles and moles to grams using a simply calculator. Plus, learn the g to mol formula and how to account for molar mass.
If you combine 100 g (or 3.706 moles) of Al (molar mass = 26.982 g/mol) and 100 g (or 3.125 moles) of O2 (molar mass = 31.999 g/mol) it will have a theoretical yield of 188.946 g (1.853 moles) of Al2O3 (molar mass = 101.961 g/mol).
30 sty 2024 · As mass/volume = molarity × molar mass, then mass / (volume × molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 × 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass.
