Molarity = moles solute/liter solution
moles solute = 7 g NaCl x 1 mol NaCl/58 g NaCl = 0.12 moles NaCl
liters of solution = 450.0 ml x 1 L/1000 ml = 0.450 liters
molarity = 0.12 moles/0.450 liters = 0.268 M = 0.3 M (one sig fig)

1st.) convert 500 mL to L
500.0 x (1mL/1000 L)=.5 L
2nd.) 0.100 M= x amount of grams/ .5 liters
.100 M x .5 liters= x amount of grams

∙ 12y agoThe molarity of sodium chloride in a solution containing 0.50 mol of sodium chloride in 500 mL of water would be 1M.
0.50 moles in 500mls means there are 1.0 moles in 1 liter.

A solution is made by dissolving 19.52 g of SnF2 into enough water to make 770 mL of solution What is the molarity of the solution?
the molarity is found by: 19.52g/770mL x 1 mole/156.7g x 1000mL/1L=0.618 mole i got 156.7g by using the chemical makeup of the solution SnF2: Sn's atomic number being 118.7 and rounding F's atomic number to 19.
How do you determine the molarity of a solution containing 18.2g C6H12O6and enough water to reach 6.3L?
Moles of solute ---------------- Liters of solution So, convert your grams to moles by dividing by the molar mass (add together the atomic masses of the solution) and then that will give you your moles. Divide that number by your 6.3 Liters. That number is your molarity.
2.431 g of h2c2o4 x 2h2o was obtained and dissolved in enough dI water to form 250.0 ml of solution what is the concentration of the resulting of h2c2o4 solution?
Molarity (concentration ) = moles of solute/Liters of solution 250.0 ml = 0.250 liters 2.431 grams H2C2O4 * 2H2O ( 1mole cpd/ 126.068 grams) = 0.01928 moles H2C2O4 * 2H2O Molarity = 0.01928 moles cpd/0.250 liters = 0.07712 Molarity

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 )
