The answer depends on how many formula units of CuSO4 you have. In one formula unit, there are 6 atoms (1 Cu, + 1 S + 4 O).
One molecule has 6 individual atoms. If the number you are looking for is much larger than that you need to know how many grams or moles of CuSO4 you are supposed to calculate.
CuSO4 isn't an element.
Copper sulfate (CuSO4) has 6 atoms and 3 chemical elements.
Copper on the Periodic Table of Elements is Cu. Copper is 1 atom. Sulphur on the Periodic Table of Elements is S. Sulphur is 1 atom. Oxygen on the Periodic Table of Elements is O. Since there is a 4 next to the O, it's 4 atoms of Oxygen. 1 Atom of Copper + 1 Atom of Sulphate + 4 Atoms of Oxygen = 6 Atoms.
Two oxygen atoms.
First it helps to know the chemical formula: CuSO4 The number in the subscripts indicate the number of atoms of an element in the compound. If there is no number, then it is implied that there is only one atom. So, there is one atom of copper, one atom of sulfur, and four atoms of oxygen; for a total of six atoms.
