The decomposition of sodium bicarbonate,
will result in the formation of sodium oxide,
and carbon dioxide,
.
Hence, carbon dioxide,
will produce with sodium oxide,
on decomposition of

Answer:
The correct answer is 2, 0M
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter):
250 ml solution----- 0,5 moles of NaCl
1000 ml solution----x= (1000 ml solution x 0,5 moles of NaCl)/250 ml solution
x= 2,0 moles of NaCl --> <em>The solution is 2 M</em>
