What is the molarity of a solution that contains 0.75 mol Naci in 3.0 L of solution? Select one: O a. 4.0 M O b. 2.3 M O d. 3.8 M O d. 0.25 M Clear my choice​

Explanation:

Molarity is a measure of concentration in moles per liter.

The solution contains 0.75 moles of sodium chloride and has a volume of 3.0 liters.

Substitute these values into the formula.

Molarity has the molar (M) as its unit. 1 molar is equal to 1 mole per liter.

The molarity of the solution is 0.25 Molar and Choice D is correct.

the answer is c.the valence of the atoms combine .
