2 Calculate the mass of sodium nitrite you need to prepare 2

2. Calculate the mass of sodium nitrite you need to prepare 250.00 ml of 0.05 N solution of sodium nitrite. Calculate the titer by sulfanilic acid of the prepared solution. Vi

Solution

For sodium nitrite, normality is equal to molarity.

So,

Moles of Sodium Nitrite needed = Molarity*Volume = 0.05*0.25 = 0.0125

Mass of Sodium Nitrite needed = Moles*MW = 69*0.0125 = 0.8625 g

Hope this helps !
