What is the molarity of the solution where 0.5 g of NaCl is dissolved to make 0.05 L of solution?
Wiz007
Given: 0.5 g NaCl; 0.05 L of solution.
1) Find the molar mass of NaCl.
(22.99) + (35.45) = 58.44 g/mol of NaCl
2) Convert grams of NaCl to moles of NaCl.
(0.5 g NaCl) X (1 mol NaCl / 58.44 g NaCl) = 0.00855578 mol NaCl
3) Use the molarity equation, M = mol / L, to solve for molarity (M).
(0.00855578 mol NaCl / 0.05 L) = 0.17 M

What is the molarity of a solution using 76 g of NaCl dissolved to make 1 L?
The molecular weight of NaCl is 58.443 g/mol. 78/58.443 is 1.300412367606 moles. It is in litres so it is 1.300412367606 molar.
When 80g of sodium hydroxide are dissolved in water to make 0.500 of a solution what is the molarity?
4m
What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
Molarity of 734 grams of lithium sulfate are dissolved to make 2500ml of solution?
Because you have 6.68 moles of Li2SO4 and 2.500 liters of water, the overall molarity of your solution is 2.67 M.
How could you make a 1.00M solution if you had a 2.00M solution of NaCl?
If we add 1 L of water to 1 L of 2 M NaCl solution will give 2 L of 1 M NaCl solution

What is the molarity of a solution containing 117 grams of sodium chloride in enough water to make a 40.0 L solution?
[117(g NaCl) / 58.5(g NaCl/mol NaCl)] / 40.0(L solution) = [117/58.5]/40.0 = 2.00(mol NaCl) / 40.0(L) = 0.0500 mol NaCl / L solution = 0.0500 M
What is the molarity of a solution made by dissolving 58.44 g of NaCl in enough water to make 1.0 L of solution?
Divide grams (mass) by molar mass to find moles58.44 (g NaCl/L) / [22.99+35.45](g NaCl/mol NaCl)= 1.000 mol/L NaCl
