Answer 2

Prepare the standard solution of 250ml 0.5M Na2CO3.

Answer:

Let's solve the answer for this.

We need the molarity of Sodium Carbonate.

so the formula morality is:

number of moles of the solute/volume of the the solution in litres.

Molarity= 0.5 M

Volume of the solution is = 250 ml

The molecular mass of sodium carbonate is = 23*2+12+16*3= 106

0.5= x*1000/ 106*250

X= 0.5*106*250/1000

X= 13.25 grams.

Answer: 13.25 grams.
