Question

If you have 5 moles of an element, how many atoms do you have?

a. 3.01 x 1024
b. 18.12 x 10 23
c. 6.02 x 1023
d. 8.3 x 1022

Answer 1

`\qquad \qquad\huge \underline{\boxed{\sf Answer}}`

Let's solve ~

`\qquad \sf  \dashrightarrow \: 1 \: mole = 6.022 * 10 {}^(23)`

`\qquad \sf  \dashrightarrow \: 5 \: moles = 5 * 6.022 * {10}^(23)`

`\qquad \sf  \dashrightarrow \: 5 \: moles =30. 110 * 10 {}^(23)`

`\qquad \sf  \dashrightarrow \: 5 \: moles \approx3.01 * 10 {}^(23)`

Therefore, the correct choice is A
