1st - molar mass is 315.4 gram per mol, not 315.4 mol. 2nd - you didn't tell how many moles is 3.9g, but according to your concentration calculations you have found it to be 0.02276 mole - which is wrong. 3rd - barium hydroxide dissociation ends up with OH-ions, not H+- so you...
Finally, add together the total mass of each element to get the molar mass of CUSO4.5H20: 12.0107 g/mol + 238.02891 g/mol + 32.065 g/mol + 71.9973 g/mol + 20.1588 g/mol = 374.26071 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in CUSO4.5H20...
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....
If you combine 169.898g (or 1 moles) of SiCl4 (molar mass = 169.898 g/mol) and 4.032g (or 0.2 moles) of H20 (molar mass = 20.159 g/mol) it will have a theoretical maximum yield of 28.086g (0.5 moles) of Si2 (molar mass = 56.171 g/mol) and 145.844g (4 moles) of HCl (...
