Suppose you have 200.0 mL of a 0.750 M sodium hydroxide solution. How many moles of sodium hydroxide are in the solution?

0.15 moles of sodium hydroxide are in the solution.

Explanation:

Molarity is a unit for expressing concentration of solutions. Molarity is defined as the number of moles of solute per liter of solution.

The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution:

Molarity is expressed in units ().

So, a molarity of 0.750 M indicates that 0.750 moles are present in 1 L of solution. Then the following rule of three can be applied: if in 1000 mL (being 1 L = 1000 mL) there are 0.750 moles, in 200 mL how many moles are there?

amount of moles=0.15

0.15 moles of sodium hydroxide are in the solution.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
