Question

How many moles are in 1.16 x 1025 atoms of H2CO3?

A. 1.87 x 1023 moles of H2CO3
B. 6.98 X 10 48 moles of H2CO3
C. 19.3 moles of H2CO3
D. 7.19 x 10 26 moles of H2CO3

Answer 1

Here, number of moles in 6.23 * 10^23 atoms = 1
So, it would be: 1.16 * 10^25 / 6.23 * 10^23 = appox. 19.3 moles

In short, Your Answer would be Option C
