How many milliliters of 0.125 M solution of CUS04 are needed to have 0.500 g of CUS04

Answer 1

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.
