Urg trying to figure this out and goodness I have a test on this subject tomorrow I need to know how to do this

anonymous · Answer

And of course for your sake :)

a1234 · Answer

Well, what I did was use the factor-label method like this:

Moles of the element * (molar mass/1 mole) = grams of the element

anonymous · Answer

Ok so there are stages of converting in this there is going from moles mass and particles and yup i remember that ok I'm working and I'll update you as soon as I finish or have ideas

@sweetburger Can you check my work?

anonymous · Answer

For uranium 59 seems correct since I believe what you have to do is multiple the mole by the molar mass to get the amount of grams

a1234 · Answer

Yep...I think the same is to be done for the other two

anonymous · Answer

Yep seems good to me
