Molarity = moles of solute/Liters of solution
10 grams of compound ( 1mol/100g ) = 0.1 mole
Molarity = 0.1 mol/1 Liter
= 0.1
0.286
This value is 0,0164 M.
true
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
30mg in 5ml is 0.03g per 5ml. Multiply this by 20 to convert to litres. 0.03*20 is 0.6g/litre. 0.6/78.96 is 0.0076 molar.

Divide 175 by 750 and multiply by 1000 to get g/l. This gives you 233.3333g/litre. The molecular weight for KNO3 is 101.1g/mol. 233.333/101.1 is 2.31 molar.
0.736 i think good luck
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
Molarity= Number of moles of solute/Liters of solution 50 grams KOH 700 ML to .7 Liters of h2o Molar Mass of KOH= 56 50 divided by 56 = .89 moles Molarity= .89 mol/.7 L = 1.27 MOLARITY
Find moles of HCl first. 1.56 grams HCl (1mole HCl/36.458 grams) = 0.0428 moles HCl Molarity = moles of solute/volume of solution Molarity = 0.0428 moles/26.8 ml = 0.00160 milli-Molarity, or more to the point; = 1.60 X 10^-6 Molarity of HCl
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
15.8/180 is 0.08777778 moles in 169ml. divide by 169, x 1000 (per litre) is 0.5194M
30mg in 5ml is 0.03g per 5ml. Multiply this by 20 to convert to litres. 0.03*20 is 0.6g/litre. 0.6/78.96 is 0.0076 molar.
You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution.
