Question

117 gms of Nacl was dissolved in water and made a solution of 2 liters calculate the molarity?​

Answer 1

Answer:

The molar mass of NaCl is 23+35.5=58.5 g/mol.

The mass of NaCl is 117 grams.

The number of moles of NaCl is  

58.5

117

​  

=2  moles.

Molarity of solution is the number of moles of NaCl present in 1 L of solution.

Hence, the molarity of NaCl is  

1L

2mol

​  

=2M
