Question

Calculate the molarity of a salt solution containing 0.36 mol of NaCl in total volume of 134 mL.

(M = mol
solute/L solution)

Answer 1

2.7mol/L

Step-by-step explanation:

We know M is in mols of solute per Litre of solution

From this, we know the eqaution is M = n/V (where is is moles of salt and V is volume of soltuon)

Plug in the values

M = 0.36mol/0.134L (remember to have volume in Litres, the question gives it in mL)

M = 2.687 mol/L
