To find the amount of NaCl in the solution, we need to convert the percentage concentration into grams and then multiply by the volume of the solution.
The percentage concentration is given as 2.0% (m/v), which means 2.0 grams of NaCl is present in 100 mL of solution.
To find the grams of NaCl in 300 mL of solution, we can use a proportion:
2 g NaCl /100 mL = x g NaCl /300 mL
Cross-multiplying, we have:
100 mL * x g NaCl = 2 g NaCl * 300 mL
x g NaCl = (2 g NaCl * 300 mL) / 100 mL
x g NaCl = 6 g NaCl
Therefore, there are 6 grams of NaCl in 300 mL of the 2.0% NaCl solution.
A 2.0% (m/v) NaCI solution contains
