We’re being asked to determine how many O atoms are in one mole of copper(II) sulfate, CuSO4.
We can calculate the number of O atoms using the following steps:
moles CusO4 (mole-to-mole comparison) → moles O (Avogadro’s number) → O atoms
Calculate the # of O atoms.
One mole of copper(II) sulfate, CuSO₄, contains___ O atoms.
A) 4
B) 6.02 x 10²³
C) 1.51 x 10²³
D) 2.41 x 10²³
E) 2.41 x 10²⁴
