Question

3 moles Li to atoms

Answer 1

Number of atoms of Li =

`1.807x10^(24)\text{ atoms}`

Step-by-step explanation

Given

moles of Li = 3 moles

Required: Number of atoms of Li

Solution

`\begin{gathered} 1\text{ mole = 6.022x10}^(23)\text{ atoms} \\ 3\text{ moles = x atoms} \\ \\ Solve\text{ for x} \\ \\ x\text{ = \lparen3 moles x 6.022x10}^(23))/1\text{ mole} \\ x\text{ = 1.807x10}^(24)\text{ atoms} \end{gathered}`
