How many milliliters of 0.125 M solution of CUS04 are needed to have 0.500 g of CUS04
The molar mass of CUSO4 is 159.62 g/mol.
First, calculate the number of moles of CUSO4 in 0.500 g:
0.500g / 159.62g/mol = 0.00313 mol
Now, use the molarity formula to calculate the volume of 0.125 M solution needed:
Moles = Molarity x Volume
0.00313 mol = 0.125 mol/L x Volume
Volume = 0.00313 mol / 0.125 mol/L = 0.025 L
Convert the volume to milliliters:
0.025 L x 1000 mL/L = 25 mL
Therefore, 25 milliliters of a 0.125 M solution of CUSO4 are needed to have 0.500 g of CUSO4.
