Number of grams in 2.0 moles of magnesium chloride?
The formula of magnesium carbonate is MgCO3. It therefore has one atom each of magnesium and carbon and 3 atoms of oxygen. The gram molecular weight is therefore 24.305 + 12.011 + 3(15.999) = 84.313. This answer to the problem is twice this value, 168.626 grams, if the number "two" is considered to be exact.
What is the molecular weight of vanillideneacetone?
The molecular weight of vanillideneacetone is 192.214g/mol.
What is the mass of 9.40 moles of magnesium chloride MgCl2?
There is 9.40 mol of MgCl2 and you want to know how many grams (g). First find the atomic weight of the molecule. Mg = 24.312 Cl = 35.453 x 2 = 70.906 MgCl2 = 95.218 g/mol Then multiply the given moles by the atomic weight of the molecule to get the mass. 9.40 mol x 95.218 g/mol = 895.05 g MgCl2
What is molecular weight of insulin?
The molecular weight of insulin is approximately 5,800 Daltons.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
How many formula units make up 11.6g of mgcl2?
To find the number of formula units of MgCl2 in 11.6g, first calculate the molar mass of MgCl2 (95.21 g/mol). Then, divide the given mass by the molar mass to find the number of moles (0.122 mol). Since 1 mol of MgCl2 contains 1 formula unit, the number of formula units in 11.6g of MgCl2 is also 0.122 mol.
If 5.25 g of MgCl2 is dissolved in 200.0 ml of solution calculate the concentration( molarity) of MgCl2, the magnesium ion, and the chlorine ion?
Atomic weight for Mg is 24.305, for Cl is 35.453. Molecular weight for MgCl2 is 24.305 + 2(35.453) = 95.211. Molarity for the MgCl2 solution made with 5.25 g of the salt diluted to 200 ml is, M = [5.25/95.211] x [1/0.200 liter] = 0.2757 Molar Assuming 100 % ionic dissociation, Molarity of Mg+2 is 0.2757 and for Cl- is twice, 0.5514
How much is 4 millimoles of magnesium in mg?
1 Mole of magnesium = 24.305 grams The 24.305 comes from the periodic table of elements. Simply find Mg and the atomic mass (the biggest number) is the same if u have 1 mole of that. So 24.305 grams x 4 = 97.22 grams

What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
