What is the molarity of a solution with 0.0858moles of a solute dissolved in 0.06kg?

To calculate the molarity of a solution, you need to know the number of moles of solute and the volume of the solution in liters.

First, convert the mass of the solution from kilograms to grams:
0.06 kg = 60 g

Next, calculate the molarity using the formula:
Molarity (M) = moles of solute / liters of solution

Given:
moles of solute = 0.0858 moles
mass of solution = 60 g

To find the volume of the solution in liters, you need to know the density of the solution. Let's assume the density is 1 g/mL.

Volume of solution = mass of solution / density
Volume of solution = 60 g / 1 g/mL = 60 mL = 0.06 L

Now, calculate the molarity:
Molarity = 0.0858 moles / 0.06 L = 1.43 M

Therefore, the molarity of the solution is 1.43 M.

Molarity = moles of solute / liters of solution

First, convert the mass of the solvent from kg to liters using the density of water (1 kg/L):

0.06 kg - (1 L / 1 kg) = 0.06 L

Now, calculate the molarity:

Molarity = 0.0858 moles / 0.06 L
Molarity = 1.43 M

Therefore, the molarity of the solution is 1.43 M.
