Calculate the molarity of a solution obtained by dissolving 1.6g NaOH

1.	Calculate the molarity of a solution obtained by dissolving 1.6g NaOH 8s 500ml water
Answer» Answer: The molecular weight of NAOH is 40 G/mol. The number of moles of NaOH 40 g/mol 5 g =0.125 moles. 500 ML WATER corresponds to0.500 L. The MOLARITY of the solution = 0.500 L 0.125 moles =0.25 M

Calculate the molarity of a solution obtained by dissolving 1.6g NaOH 8s 500ml water

Answer»

Answer:

The molecular weight of NAOH is 40 G/mol.

The number of moles of NaOH

40 g/mol

5 g

=0.125 moles.

500 ML WATER corresponds to0.500 L.

The MOLARITY of the solution =

0.500 L

0.125 moles

=0.25 M
