Answer:
2.34 M
Explanation:
The molecular weight of sodium hydroxide is 39.997 g/mol.That is, 1 mole weights 39.997 g
You have
23.4 g so you have
23.4g /39.997 g/mol=0.585 moles
These 0.585 moles are present in 250 ml and 250 ml is equivalent to 0.25 liters.
Molarity is moles per liter.
molarity=moles/litre
molarity=0.585 moles/0.25 L
molarity =2.34 M
