CM=n/V

100 g of a given solution has a volume of:

V (HCl) = 100/1.19 = 84.03 ml

n = m/M

M (HCl) = 36.5 mol/l

n (HCl) = 37/36.5 = 1.01 mol

CM (HCl) = 1.01/84.03 = 0.01 mol/l

a.) Calculate the molarity of 0.150 mol of Na<sub>2</sub>S<sub> </sub>in 1.10 L of solution? b.) calculate the molarity of 32.9g of MgS in 763 mL of solution?

a) molarity = moles / volume Molarity = 0.150/1.10 = 0.136Mb) moles = 32.9/56.38 = 0.583molesVolume = 763ml = 0.763LMolarity = moles / volume Molarity = 0.583/0.763 = 0.764 M

A concentrated solution of HCl has a molarity of 10.0 M. You add 23.50 mL to a flask and then dilute with water. The mass of the final solution is 125.0 g. What is the mass percent of HCl ?

Mass percent essentially means g of HCl/total grams of solution (x100%). So, in this problem we already know the total mass = 125.0 g. If we can find the mass...

Calculate the molarity of a dilute solution made by diluting 17 mL of 0.62 M concentrated solution to a final total volume of 928 mL

M1V1 = M2V2M2 = 17×0.62/928= 0.01136

Concentrated Hydrochloric acid is commonly sold as 12.0 M HCL and its density is 1.18 g/cm^3 . Calculate: (a)the Molality of the solution. (b) the weight percent of HCL in the solution

The molality, b, of a solution is the amount of substance (in mol) of solute, divided by the mass (in kg) of the solvent (not the mass of the solution):...

Calculate the weight of water in a 1.5 liters 95% nitric acid (HNO3) that has a specific gravity of 1.82. Express the concentration of solution in terms of Molarity, Normality and molality.

1) density = m/VMass of HNO3 = density x V = 1.82 x 1.5 = 2.73 kg% = (100 x m(solvent))/ (m(solvent) + m(solute))m(HNO3) = 95/100 x 2.73 = 2.59...

what is the molarity of a HCl solution that contains 6.40g of HCl in 477mL of solution? answer in units of M

M(HCl) = 35.5 + 1 = 36.5 (g/mol) n(HCl) = m/M = 6.4 / 36.5 = 0.175 (mol) c(HCl) = n / c = 0.175 / 0.477 = 0.37 (mol/l)...
