Answer:
Concentration solution A was 0.5225 M
Explanation:
10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B
According to laws of dilution- 
where, 
and 
are concentration of solution A and B respectively
and 
are volumes of solution A and B respectively
Here = 0.1045 M, = 50.00 mL and = 10.00 mL
Hence, 
So, concentration solution A was 0.5225 M
