What is the total number of atoms contained in 2.00 moles of oxygen?

Hey there!

One mole contains 6.022 x 10²³ atoms.

We have 2 moles.

2.00 x 6.022 x 10²³ = 1.20 x 10²⁴

There are 1.20 x 10²⁴ atoms of oxygen contained in 2.00 moles of oxygen.

Hope this helps!

explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
