converting J to kJ/mol

Postby Katherine Wu 1H » Tue Nov 05, 2019 4:28 pm

converting 4.89x10^-17 J to kJ/mol

first convert J to kJ by multiplying by 0.001.
I'm not sure how to do the next part? Do I divide or multiply the number by avogadro?

You would then divide by avogadro's number because 1 mol = 6.022 x 10^23 and in this case with dimensional analysis it would allow the moles to cancel. Hope this helps!

To convert 4.89x10^-17 J to kJ/mol, you would indeed multiply by 0.001 to convert fromJ to kJ, which would leave you with kJ. If you divide by avogardo's number, it would cancel out the kJ which would leave you with moles.
