Calculate the number of oxygen atoms in a 150.0 g sample of forsterite (Mg2SiO4).
If 5.98 g of sodium react with water to form 0.26 g of hydrogen and 10.40 g of sodium hydroxide, what mass of water was consumed in the reaction?
Magnesium has three naturally occurring isotopes. One has an isotopic abundance of 78.99% and a mass of 23.985042 amu, and the second one has an isotopic abundance of 10.00% and a mass of 24.985837
