Question

Urgent!! Can anyone please help me with this?

What is the molarity of an NaCl solution if 0.30 moles of salt are dissolved in 200.0 milliliters of water?

Answer 1

Molarity = 1.5 M

Step-by-step explanation:

Given data:

Molarity of solution = ?

Number of moles of NaCl = 0.30 mol

Volume of water = 200 mL (200/1000 = 0.2 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 0.30 mol / 0.2 L

Molarity = 1.5 M
