Answer:
There are 0.5 moles of rubidium
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
