How many uranium atoms do you have with 0.70 moles of uranium atoms?

Answer 1

To find the number of uranium atoms in 0.70 moles, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms per mole. Multiplying the number of moles by Avogadro's number gives:

(0.70 , \text{moles} \times 6.022 \times 10^{23} , \text{atoms/mole} \approx 4.21 \times 10^{23} , \text{atoms}).

Thus, there are approximately (4.21 \times 10^{23}) uranium atoms in 0.70 moles.
