Question

There are about 6.022 x 10atoms of hydrogen in a mole of

hydrogen. How many hydrogen atoms are in 3.5 x 10' moles of hydrogen

Answer 1

There are approximately 2.1077 x 10^32 hydrogen atoms in 3.5 x 10^8 moles of hydrogen.

Answer 2

There are 2.1117 x 10^47 hydrogen atoms in 3.5 x 10^23 moles of hydrogen.

Step-by-step explanation:

To find the number of hydrogen atoms in 3.5 x 1023 moles of hydrogen, we can use the conversion factor that there are 6.022 x 1023 atoms of hydrogen in a mole of hydrogen. So, we can set up the following equation:

3.5 x 1023 moles H2 x 6.022 x 1023 atoms H2/1 mole H2 = 2.1117 x 1047 atoms of hydrogen.
