What mass of solute is needed to make 100 g of 3.4% solution?
Question
What mass of solute is needed to make 100 g of 3.4% solution?
Solution
To find the mass of the solute needed to make a 100g of 3.4% solution, you can use the formula for percent concentration by mass, which is:
(mass of solute / mass of solution) * 100% = percent concentration
In this case, you want to find the mass of the solute, so you rearrange the formula to solve for that:
mass of solute = (percent concentration / 100%) * mass of solution
Substitute the given values into the formula:
mass of solute = (3.4 / 100) * 100g
mass of solute = 0.034 * 100g
mass of solute = 3.4g
So, you need 3.4g of solute to make a 100g of 3.4% solution.
