1.1
Calculate the concentration of the following solutions:
2 mol of table salt is dissolved in 250 cm³ of water.

Answer 1

8M

Step-by-step explanation:

Molar Concentration = moles of solute / litres of solution

Converting units:

250cm^3 = 0.25L

Substituting;:

Molar Concentration = moles of solute / litres of solution

Molarity = 2 / 0 25

Solving:

Molar Concentration = 2 / 0.25

Molar Concentration = 8

Molar Concentration = 8M

(M is molar)
