How many copper atoms are in 5.6 moles of #Cu_2O#?

Answer 1

I found #6.74×10^(24)# Cu atoms.

In one mole you have Avogadro's number (#6.022×10^(23)#) of objects, in this case 'formula units' of #Cu_2O#.
So, in #5.6# moles we have:
#5.6×6.022×10^(23)# formula units of #Cu_2O#, each one with #2# Cu atoms giving:
#2×5.6×6.022×10^(23)=6.74×10^(24)# atoms of Cu...

Answer 2

Since there are two copper atoms in each Cu2O molecule, there are two moles of copper atoms in one mole of Cu2O. Therefore, in 5.6 moles of Cu2O, there are (5.6 \times 2 = 11.2) moles of copper atoms. Since one mole contains Avogadro's number of atoms (approximately (6.022 \times 10^{23})), the number of copper atoms in 5.6 moles of Cu2O is approximately (11.2 \times 6.022 \times 10^{23} = 6.74 \times 10^{24}) copper atoms.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
