little unsure on some exponent type math I did...
when I did the volume I took (4/3)(pie)(r)^3 basically just plugged in (1.2X10^-15) into my figures and it kicked out something approaching:
volume = - 2.44 X 10^7
I then divided Mass/Volume:
(1.67X10^-27)/(-2.44X10^7) = 6.84X10^-35
am I using these exponents correctly in scientific notation and getting the approximate right answers?
Thanks
Brian

A proton which is the Nucleus of a hydrogen atom can be modeled as a sphere with a diameter of 2.4 fm and a mass of 1.67X10^-27kg
(a). Determine the density of the proton
(b). state how your answer to part (a) compares with the density of Osmium, given in Table 14.1 (that was Osminum 22.6X10^3)
My formulas
Density = P = M/V Mass per unit volume
Volume of sphere = (4/3)(pi)(r)^3
my data:
Proton
Mass 1.67X10^-27kg
Diameter 2.4fm = (if I did scientific notation correctly) 2.4X10^-15
radius 1.2X10^-15
Osminum
Mass 22.6X10^3
I then plugged things in
(4/3)(pi)(1.2X10^-15)^3 = -2.44X10^7
Then divided mass by volume
(a). (1.67X10^-27)/(2.44X10^7) = 6.84X10^-35
(b). Density of proton is way way way smaller than Osminum
Ugggg.... this stuff is so hard to type which is why I asked a about a program in software part... maybe I should start trying to use word to do all this I just get slowed down a ton hunting for symbols!
Thanks,
Brian
