Question

What is the number of atoms of hydrogen in 1.00 pg of humulone?

Answer 1

Well, `1*pg-=1xx10^-12*g=1xx10^-15*kg.....`. I do not know what humulone is.

Explanation:

And as always, to find the number of atoms....we take the product...

`"Moles "xx" Molar quantity"`. And so if we had `1xx10^12*g` of hydrogen, we could work out the number of hydrogen atoms.

`(1xx10^-12*g)/(1.00794*g*mol^-1)xx6.022xx10^23*mol^-1=6.0xx10^11` individual hydrogen atoms....
