Calculate the concentration of a solution with 0.8g of NaCl in 280mL of water.

The molarity of NaCl solution is 0.0489 M

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

.....(1)

We are given:

Given mass of NaCl = 0.8 g

Molar mass of NaCl = 58.44 g/mol

Volume of the solution = 280 mL

Putting values in equation 1, we get:

Hence, the molarity of NaCl solution is 0.0489 M

so whats the answer tell me
