Question

The total charge of a nucleus = 92*1.6*10^-19
Mass of Nucleus = A * 1.67 * 10^-27
Rearrange to find A, then subtract the number of protons, the answer should be about 146.
Can someone help me find A?

Answer 1

A =146 but how do i get to that?

Answer 2

The specific charge is 3.7*10^7

Answer 3

hey is the value of A 188?
bcoz,the first statement says that there are 94 protons .......
in the next statement,A=protons+neutrons
in the nucleus no of protons=no of neutrons
so, A=94+94=188.

Answer 4

No A = 146. I am looking to find out how i arrive at that number. Sorry there are 92 protons

Answer 5

lol.yeah 92!

Answer 6

specific charge=charge/mass
so \[(92*1.6*10^-19)/(A*1.67*10^-27) =3.7*10^7\]
calculate and u get A=238.23
A-92=146.23

Answer 7

which standard are u?

Answer 8

I am only Gcse

Answer 9

Gcse means?

Answer 10

Below A-level?

Answer 11

just calculate or use a scientific calculator!!!!

Answer 12

I don,t think you understand what i am saying. You have given me the answer 3.7*10^7. That is ok. But how do you get the answer 238?

Answer 13

?

Answer 14

The specific charge of 3.7*10^7 is for Uranium 238?
