#1.74638 * 10^24# hydrogen atoms

In 1 mole of any element we know that there are #6.022 * 10^23# particles.

#therefore# in #1.45# moles there are:

#1.45 * 6.022 * 10^23 = 8.7319 * 10^23# particles.

Hydrogen is diatomic going around as #H_2#

#therefore# #2 * 8.7319 * 10^23 = 1.74638 * 10^24#

#~~8.73*10^23# atoms of hydrogen

Assuming that you are talking about single, unpaired #(H)# atoms (which is unlikely), then we have the following:

In one mole of hydrogen atoms, there exists approximately #6.02*10^23# hydrogen atoms.

So, in #1.45# moles of hydrogen atoms, there will be

#1.45*6.02*10^23~~8.73*10^23# hydrogen atoms.
