Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

What is the molar mass of sodium hydroxide? | Study

Mar 31, 2020· We have M(OH)2, and we know that 32.8% of the mass is oxygen, so using the g-mol masses of oxygen and hydrogen, we know that 32/(M+32+2) = 0.328 or 32/0.328 = M+34 So M =32/0.328 – 34 = 63.56 Which means that M is copper, Cu, with a g-mol mass of ...

What would be the proper way to solve a titration problem ...

You can make up some arbitrary number for the mass of the hydroxide. Let's say you have 100g of M(OH)2. If 32.8% of the mass is oxygen, then 32.8 g of the sample is oxygen (since it's out of 100 g) the remainder of the sample contains the metal and 2 moles of hydrogen. 100g-32.8g =67.2 g. 67.2 g = M + 2H. the molar mass of H is 1.01. 67.2 g = M ...
