What is the molarity of a solution that contains 0.50 mole of NAOH in 0.50 liter of solution?
1. 1.0 M
2. 2.0 M
3. 0.25 M
4. 0.50 M

Respuesta :

molarity=moles/litre therefore if you have .5moles in .5 litres, molarity is simply 0.5/0.5 which would equal 1

Answer:

The correct option is 1.

Explanation:

Molarity (also called molar concentration) is the number of moles of a solute present in 1 litre of a solvent. It is useful in determining the concentration of a solute in a solvent

Hence, the formula for molarity (M) is

Molarity = number of moles (n) ÷ volume (in litres or dm³)

Hence, M = n/V

M = 0.5 ÷ 0.5

M = 1.0 M or 1.0 mol/L or 1.0 mol/dm³
