Answer:
[tex] 2.04782 * 10^{23}[/tex] atoms .
Step-by-step explanation:
Given : 0.34 moles of strontium.
To find : How many atoms are in 0.34 moles .
Solution : We have given that 0.34 moles
1 mole = [tex]6.023 * 10^{23}[/tex] atoms .
0.34 moles = [tex]0.34\ *\ 6.023 * 10^{23}[/tex] atoms .
0.34 moles = [tex] 2.04782 * 10^{23}[/tex] atoms .
Therefore, [tex] 2.04782 * 10^{23}[/tex] atoms .
