If 53g Na2CO3 is dissolved in 500 ml solution. Find the Molarity of Na...
First, we need to calculate the number of moles of Na2CO3 present in the solution:
Moles of Na2CO3 = Mass / Molar mass
= 53g / (2 x 23g/mol + 12g/mol + 3 x 16g/mol)
= 0.5 moles
Next, we need to calculate the number of moles of Na+ ions present in the solution. Each molecule of Na2CO3 contains 2 Na+ ions, so the total number of moles of Na+ ions is:
Moles of Na+ = 2 x Moles of Na2CO3
= 2 x 0.5 moles
= 1 mole
Finally, we can calculate the molarity of Na+ ions by dividing the number of moles by the volume of the solution in liters:
Molarity of Na+ = Moles of Na+ / Volume of solution in liters
= 1 mole / 0.5 liters
= 2 M
Therefore, the molarity of Na+ ion is 2 M.
Moles of Na2CO3 = Mass / Molar mass
= 53g / (2 x 23g/mol + 12g/mol + 3 x 16g/mol)
= 0.5 moles
Next, we need to calculate the number of moles of Na+ ions present in the solution. Each molecule of Na2CO3 contains 2 Na+ ions, so the total number of moles of Na+ ions is:
Moles of Na+ = 2 x Moles of Na2CO3
= 2 x 0.5 moles
= 1 mole
Finally, we can calculate the molarity of Na+ ions by dividing the number of moles by the volume of the solution in liters:
Molarity of Na+ = Moles of Na+ / Volume of solution in liters
= 1 mole / 0.5 liters
= 2 M
Therefore, the molarity of Na+ ion is 2 M.

If 53g Na2CO3 is dissolved in 500 ml solution. Find the Molarity of Na...
Solute=53g
mole of solute=53/106
=0.5 mol
solution in liter=500/1000=0.5
Na ion present in solution is =2
(CO3)- ion present in solution=1
Then,
Molarity=no.of mole of ion/volume of solution in liter
1.molarity of Na ion
M=2/0.5
M=4
2.molarity of CO3 ion
M=1/0.5
M=2
mole of solute=53/106
=0.5 mol
solution in liter=500/1000=0.5
Na ion present in solution is =2
(CO3)- ion present in solution=1
Then,
Molarity=no.of mole of ion/volume of solution in liter
1.molarity of Na ion
M=2/0.5
M=4
2.molarity of CO3 ion
M=1/0.5
M=2
