What is the Na+ concentration in each of the following solutions:
3.05 M sodium sulfate: _______M
1.18 M sodium carbonate: ______M
0.685 M sodium bicarbonate: ______ M
(b) What is the concentration of a lithium carbonate solution that is 0.695 M in Li+? _______ M
a)
1)
Given:
[Na2SO4] = 3.05 M
So,
[Na+] = 2*[Na2SO4]
= 2*3.05 M
= 6.10 M
Answer: 6.10 M
2)
Given:
[Na2CO3] = 1.18 M
So,
[Na+] = 2*[Na2CO3]
= 2*1.18 M
= 2.36 M
Answer: 2.36 M
3)
Given:
[NaHCO3] = 0.685 M
So,
[Na+] = 1*[NaHCO3]
= 0.685 M
Answer: 0.685 M
b)
Given:
[Li+] = 0.695 M
So,
[Li2CO3] = [Li+]/2
= 0.695/2
= 0.3475 M
Answer: 0.348 M
