### Molar Mass to Kg

How would we convert from g/mol to kg if the element is unknown meaning we don't know the mass of the element?

I believe you would divide by Avogadro's number, then convert the grams to kilograms by adding *10^3.

You would need to divide by Avogadro's number to get the weight in grams and then multiply by 10^3 to convert to kg. But I'm assuming that if you're converting the mass, the mass of the element is given?

From mol you would multiply by avogadro's number which would be 6.0221 x 10^23 and then multiply by 10^3 to convert from g to kg.

Make sure you divide since the units of Avogadro's number is mol^-1. If you multiply it will be incorrect.

You'd divide by 6.0221 x 10^23 (Avogadro's Number), and then to convert from grams to kilograms by multiplying 10^3.

Divide by Avogrado's number and then multiply g to get kg
