What mass of solute is needed to make 100 g of 3.4% solution?
Answer (1)
To determine the mass of solute needed to make a 100 g solution with a concentration of 3.4%, we use the formula:[tex]\text{Mass of solute} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Mass of solution}[/tex]Substituting the values, we have:[tex]$ \text{Mass of solute} = \left( \frac{3.4}{100} \right) \times 100 , \text{g} $[/tex]Calculating this gives:[tex]$ \text{Mass of solute} = 0.034 \times 100 , \text{g} = 3.4 , \text{g} $[/tex]Thus, to make a 100 g solution with a concentration of 3.4%, you need 3.4 grams of solute.
