How many ions are present in 30.0 ml of 0.600 m na2co3 solution?
THIS IS THE BEST ANSWER ๐
Concentration of Na2CO3 = 0.600 M.
Volume of Na2CO3 = 30.0 ml = 0.030 L.
Polarity = dissolved moles / volume of solution
Now,
moles of Na2CO3 = M * V = 0.600 * 0.030 = 0.018 moles
Na2CO3 โ 2Na ^ + + CO3 ^ 2-
By stoichiometry:
1 mole of Na2CO3 produces 2 moles of Na + ion
Thus, 0.018 moles of Na2CO3 would dissolve: 2 * 0.018 = 0.036 moles of Na + ion.
Now,
1 mole of Na + has 6.023 * 10 ^ 23 ions
therefore, 0.036 moles of Na + would correspond to:
= 0.036 * 6.023 * 10 ^ 23 = 2.17 * 10 ^ 22 Na + iain
