Question

Calculate number of moles in
3.01 X 10^23 atom of moles
of rubidium

Answer 1

There are 0.5 moles of rubidium

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23}6.023×10

23

of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}=\frac{3.01\times 10^{23}}{6.023\times 10^{23}}=0.5molesNumber of moles=

avogadro’s number

Given atoms=

6.023×10

23

3.01×10

23

=0.5moles

Thus there are 0.5 moles of rubidium
