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 ~

$\qquad \sf  \dashrightarrow \: 1 \: mole = 6.022 \times 10 {}^{23}$

$\qquad \sf  \dashrightarrow \: 5 \: moles = 5 \times 6.022 \times {10}^{23}$

$\qquad \sf  \dashrightarrow \: 5 \: moles =30. 110 \times 10 {}^{23}$

$\qquad \sf  \dashrightarrow \: 5 \: moles \approx3.01 \times 10 {}^{23}$

Therefore, the correct choice is A
