What is the mass of 6.80 moles of magnesium chloride MgCl2 express the value and units?
6,8 x 95,211 g (molar mass of anhydrous MgCl2)The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
The formula of 20 moles of sodium chloride?
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
How many moles in 22.6g of sodium chloride?
The formula mass of sodium chloride is 58.5 Amount of NaCl = 22.6/58.5 = 0.386mol
How many moles of ZnCl2 will be produced from 28g of Zn assuming CuCl2 is available in excess?
Ok, so we have... Zn + CuCl2 -> ZnCL2 + Cu And we are given that we have 28g of Zn (Zinc). But the question calls for moles of ZnCl2. So, the first step is to convert grams to moles of Zn. We will need to find the AMU (Atomic Mass Units) that a Zn atom's mass. A Zn atom has a mass of 63.546 AMU. Now, we take the given mass and divide it by the mass of the atom to get the moles of reactant we have. 28g/63.546AMU≈ .4406257moles If your teacher/ professor cares about sig figs, then it's .44 because you only have two sig figs from the given from the given mass of Zn (28g). Now, the easy part. What is the ratio of Zn atoms on the reactant side to Zn atoms on the product side? 1:1 And since we have excess CuCl2 Nothing else limits the reaction. So, .44 (or how ever far your teacher wants you to round) moles of Zn reactants in a ideal environment (you will learn later that no reaction is 100% and that there are reactants always left over and how to solve for that) produces .44 moles of ZnCl2.
What is the mass in grams of 1.05 moles of AlCl3?
The answer is 144,007 g for the anhydrous aluminium chloride.
Which is the mass of 8 moles of sodium chloride?
Sodium chloride has a molar mass of about 58.5 g/mol. So multiply 8 moles by molar mass to get about 468 grams.

How many grams of sodium are needed to produce 5.3 moles of sodium chloride?
molecular formula for sodium chloride = NaClIf the mole (n) for NaCl = 5.3 moles, then the mole of sodium (Na) = 5.3 moles as well. 1 to 1 ratio mass = moles X molar mass m = 5.3 x 22.9 = 121.37 grams of sodium in 5.3 moles of sodium chloride
