Question

Assume the sun is mostly composed of hydrogen atoms. Assume the mass of the sun is 1.7e30 kg. and the mass of a hydrogen atom is 1.672e-27 kg.

how many atoms are there in the sun.

Answer 1

divide

Answer 2

i did but it still says its wrong

Answer 3

i am assuming that that is scientific notation and actually means
\[1.7\times 10^{30}\] and
\[1.672\times 10^{-27}\]

Answer 4

so divide and subtract the exponents

Answer 5

1.672 X 10^-27

Answer 6

what do u mean

Answer 7

\[\frac{1.7\times 10^{30}}{1.672\times 10^{-27}}\]

Answer 8

that doesnt work tho!!!

Answer 9

so you have two jobs: divide the numbers, i get
\[1.0167\times 10^{30+27}=1.067\times 10^{57}\]

Answer 10

divide the numbers out front
\[1.7\div 1.672=1.067\] and then subtract the exponents
\[30-(-27)=30+27=57\]

Answer 11

its saying thats wrong
