How many atoms are in 20.6 moles of curium
Harman [31]

Answer: 1.24 × 10^25

Explanation:

\frac{20.6 moles}{1} × \frac{6.022 * 10^{24} }{1 Mole}

Using our knowledge in unit conversions, we know the mole units cancel each other out and all there's left is the atom unit. From here we can multiply the fractions and eventually we end with the number 124.0532 × 10^23

According to the scientific notation rules, the number to the left of the decimal cannot exceed 10 so we have to move the decimal to the left two spaces. With this change, we also have to change the exponent of the 10. Because we moved the decimal point two spaces to the left, that means we have 10^25.
