One gram of palladium has 5.66×10^21 atoms, and each palladium atom has 46 electrons. How many electrons are contained in 7.00g of palladium? The elemental charge is1.6×10^−19C. Answer in units of electrons.

The answer is 1.82252x10^24 for Part A. i need help with part B.

b)What is the total charge of these electrons? Answer in units of C.

I Did 1.82252x10^24 x 1.6x10^-19 and i got 291603.2 but it's wrong. can someone help me with this part?

1 answer

7grams * 5.66*10^21atoms/gram * 46e/atom
= 1.82252*10^24 Electrons.

b. 1.82252*10^24e * 1.6*10^-19C/e =
2.916*10^5 C. = Your answer.
