Answer:
[tex]\boxed{\text{4.00 mol}}[/tex]
Explanation:
Use Avogadro’s number to convert formula units of RbNO₃ to moles of RbNO₃.
1 mol RbNO₃ ≡ 6.022 × 10²³ formula units RbNO₃
Moles of RbNO₃ = 2.41 ×1 0²⁴ × [tex]\dfrac{1 }{6.022\times10^{24} }[/tex] = 4.00 mol RbNO₃
There are [tex]\boxed{\textbf{4.00 mol}}[/tex] of RbNO₃ in 2.41 × 10²⁴ formula units.
