Calculate the amount of CuSO4 needed to make 5ml of 5% CuSO4.5H2O
To calculate the amount of CuSO4 needed to make a 5% CuSO4.5H2O solution in 5ml, we need to follow these steps:
Step 1: Determine the amount of CuSO4.5H2O needed:
To find the amount of CuSO4.5H2O needed, we need to know the concentration of the solution. In this case, the concentration is 5%. The concentration is expressed as the percentage by weight per volume (w/v). Therefore, 5% CuSO4.5H2O means there are 5g of CuSO4.5H2O dissolved in 100 ml of solution.
Step 2: Calculate the amount of CuSO4.5H2O needed in 5 ml:
To find the amount of CuSO4.5H2O needed in 5 ml, we can set up a proportion using the concentration from step 1:
(5g CuSO4.5H2O / 100 ml) = (x g CuSO4.5H2O / 5 ml)
Solving for x, we get:
x = (5 g CuSO4.5H2O * 5 ml) / 100 ml
x = 0.25 g CuSO4.5H2O
Therefore, 0.25g of CuSO4.5H2O is needed to make 5ml of a 5% CuSO4.5H2O solution.
