How many grams in 1.90 moles of K?
To convert from moles to grams, we need to use the molar mass of the element. The molar mass of potassium (K) is approximately 39.10 g/mol. So, for 1.90 moles of K, the mass would be 1.90 moles * 39.10 g/mol = 74.29 grams.
How may grams is in 625 mg?
1 milligram (mg) = .001 grams (g) = 1/1000 grams Therefore, 625 mg * 1/1000 grams = .625 g which is less than 1 gram (g).
How many grams of KCL is produced from 2.5 g of K and 1 g of Cl?
The chemical formula for potassium chloride (KCl) is K + Cl. Since the molar ratio of K to Cl is 1:1, the limiting reactant will determine the amount of KCl produced. In this case, 1 g of Cl is the limiting reactant, so 1 g of KCl will be produced from 2.5 g of K and 1 g of Cl.
What is the mass of potassium chloride when 6.75 g of potassium reacts with an excess of chlorine gas?
Balanced equation and potassium limits and drives the reaction.2K + Cl2 -> 2KCl6.75 grams K (1 mole K/39.10 grams)(2 mole KCl/2 mole K)(74.55 grams /1 mole KCl)= 12.9 grams potassium chloride produced==============================

How many grams of potassium are in 12.5 g potassium dichromate?
potassium dichromate- K2Cr2O7 12.5 grams K2Cr2O7 *(1 mol K2Cr2O7/294 grams K2Cr2O7)= .0425 mols K2Cr2O7 There's two mols of K (potassium) for every 1 mol of K2Cr2O7 (Potassium Dichromate) so you multiply the K2Cr2O7 by two to get mols of K .0425 mols K2Cr2O7*(2 mols K/1 mol K2Cr2O7)=.085 mols K Multiply by the molar mass of K to get grams .85 mols K*(39 grams/1 mol K)= 3.32 grams potassium
