Answer:
2.3 g NaCl
Explanation:
Given the concentration of the NaCl solution = 0.92% (w/v)
It means that 0.92 g of NaCl is present in 100 mL of water.
Thus,
100 mL of water contains 0.92 g of NaCl
To find, amount of NaCl in 250 mL of water
So,
1 mL of water contains 
of NaCl
250 mL of water contains 
of NaCl
<u>2.3 g of NaCl is present in 250 mL of this solution.</u>
