Answer:
Total volume is 625 mL
Explanation:
We use the 6 % (m/v) data which is a sort of concentration. This percent means that the solution has 6 g of solute in 100 mL of solution
So we make a rule of three:
6 g of solute (NaCl) are in 100 mL of solution
Therefore, 37.5 g are in (37.5 .100) / 6 = 625 mL
Answer:
We make a 6.00 % (m/v) NaCl solution by dissolving 37.5 grams NaCl in 625mL.
Explanation:
Step 1: Data given
Mass/ volume % of a NaCl solution = 6.00 %(m/V)
Mass of NaCl in this solution = 37.5 grams
Step 2: Calculate the volume
Since 1.00 % (m/V) = 1.00 gram NaCl/ 100 mL
A 6.00 % (m/V) = 6.00 grams NaCl / 100 mL
But since the total mass NaCl = 37.5 grams, this means to have the same mass % ( 6.00 %) we have to increase the volume
37.5 / 6 = 6.25
We have to multiply the total volume of 100 mL by 6.25
100 mL * 6.25 = 625 mL
We make a 6.00 % (m/v) NaCl solution by dissolving 37.5 grams NaCl in 625mL.
