Question

what is the molarity of a dolution in which 5.6 moles of sodium nitrate is dissolved in water to a final volume of 4.9L

Answer 1

Molarity of a solution is the moles of solute present in 1 L solution.

Given the moles of sodium nitrate = 5.6 mol

Volume of solution = 4.9 L

Molarity of the solution =
`(5.6 mol)/(4.9 L) = 1.143 mol/L`

Answer 2

Molarity of the given solution is 1.14 M

Step-by-step explanation:

Molarity of a solution = (Number of moles of solutes)/(volume of solution in litre)

Here solute is sodium nitrate and solvent is water.

Total volume of solution is 4.9 L.

So molarity of solution = (5.6 moles)/(4.9 L) = 1.14 M
