Please explain the steps, I'm a bit lost on this concept...and of course, the answer.lol
Thank you so much!

A mole is the gram equivalent of the molecular mass of a substance.
The molecular mass of Uranium is a bit over 238 (it is the average of all the isotopes). So 1 mole would be 238 grams (get the exact number from your periodic table.)
Multiply this by 0.0050 and you are done

The mass of a mol of any factor is the atomic weight in grams. Atomic weight of uranium is 238.02891, so a mol of uranium might have a mass of 238.02891 grams. you have 0.0.5 mol of uranium 238.02891 grams/mol situations 0.0.5 mol equals a million.one hundred ninety grams

well, basically you set .0050 mol Uranium x 238.03 g of Uranium (this # is from your periodic table) then divided by 1 mol of Uranium. since it's just one, all you have to do is multiply .0050 by 238.03grams of Uranium. you should get approximately 1. 19g Ur. i learned this in honors chem last year and we're reviewing this again in ap chem this year. sorry i can't explain it to you that well through this. please pick me as the best answer. thanks.

.0050mol (238.03g/mol)
1.19 g U
The 238.03 is the atomic mass fromt the periodic table.
