Guys, I'm calculating mass for grams and I have to do two conversions I know that.

So I'm given 1.04*10^24 atoms of Kr....

So I'm supposed to do 1.04*10^24/6.02*10^23

Then multiply by mm=83.80 for Kr...


But, how do I do the first conversion on my calculator? I keep getting an error.

Blleeeeeeeez anybody, lol, I want to sleep already this is ridiculous.

LOL, I'm doing mole calculations, I need to find the mass in grams in 1.04*10^24 atoms of Kr.

Get it now? :D

Is 3.485*10^-5 the ans?
 
. . .
1.04 * 10^24 = 10.4 * 10^23

so

1.04 * 10^24 / 6.02 * 10^23 = 10.4 * 10^23 / 6.02 * 10^23 = 10.4 / 6.02 = 1.73

Thank you much sir! :)

Stupid thing wouldn't let me punch the equation without getting error until I simplified it. :D

Now it worked. So final answer =144.97 :D
