How many grams of CuSO4 must be dissolved in 100 mL of total solution to create a 0.25 M solution of CuSO4?

A) 4 g

B) 25 g

C) 40 g

D) 159 g

A) 4 g

Explanation:

Data:

V  =100 mL = 0.1 L

M  = 0.25M

g = ?

Molarity

The moles are cleared from this equation:

Through the molecular weight, the grams of CuSO4 are calculated, knowing that the molecular weight of CuSO4 is 160 g/mol.

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
