What is the molarity of a solution containing 56 grams of solute in 959mL of solution?

Answer 1

Calculating molarity of this solution requires the variables of solute mass (in kilograms), molecular weight of the solute (in kilograms per mole), and solution volume to be known (in liters). In this example we only have the variables of a mass of .056 kilograms and volume of .959 liters.

Answer 2

Molarity = moles of solute/volume of solution

You do not name the solute, so one can not calculate the moles.

Added:From this, only the MASS concentration (g/L) can be calculated, 56 g / 0.959 L = 58.4 g/L

For the molar concentration (mol/L) one should divide that value by the molar mass of the compound (which is unknown in thisquestion)

Answer 3

The first step is to convert the mass of solute to moles, using the molar mass of the solute. Then, you divide the moles of solute by the volume of solution in liters (959mL = 0.959L) to calculate the molarity. In this case, 56g of solute (let's say it's NaCl with molar mass of 58.44 g/mol) would be 0.955 mol, and the molarity would be 0.995 M.

Answer 4

It depends what the solute is. There is no way to determine the molarity without knowing that piece of information.
