SUMMARY
The discussion centers on a homework problem involving a calculation that yields a density of 4.5*10^22 /m^3, which the user converts to 4.5*10^16 /cm^3. The user initially suspects an error in the textbook's intermediate steps but later realizes a mistake in their own calculation using a handheld calculator. The final correct calculation involves the formula (8*3.14*((2*9.11*10^31)^1.5)/(3*(6.625*10^-34)^3))*(1.6*10^-19)^1.5, which results in a significantly larger number due to a previously overlooked negative sign in the exponent.
