Calculate concentration of each ion , when 25.3g of Na2Co3 is dissolve

1.	Calculate concentration of each ion , when 25.3g of Na2Co3 is dissolved in 100 ml of solution
Answer» Answer: NUMBER of moles of NA 2 CO 3 = 106 25.3 =0.239 moles Molarity of SOLUTION= 0.25 0.239 =0.956mol/litre Na 2 CO 3 ⟶2Na + +CO 3 2− ∴ CONCENTRATION of CO 3 2− =0.956M Concentration of Na + =2×0.956=1.912M

Calculate concentration of each ion , when 25.3g of Na2Co3 is dissolved in 100 ml of solution

Answer»

Answer:

NUMBER of moles of NA

106

25.3

=0.239 moles

Molarity of SOLUTION=

0.25

0.239

=0.956mol/litre

⟶2Na

+CO

2−

2−

=0.956M

Concentration of Na

=2×0.956=1.912M
