Question

3.011×10*23 molecules of orygen​

Answer 1

Answer:

Molar mass tells us about the weight of one mole of something. And one mole is 6.022 * 10^23 atmos/molecules (Avogadro's number). So 6.022 * 10^23 Oxygen atoms is 16 g (1 mole * molar mass)

Answer 2

Answer:

$\frac{3.011 \times {10}^{23} }{6.022 \times {10}^{23} } = 0.5moles \: of \: oxygen$
