Need help with chemistry urgently

[Dem!god]

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.

have you heard any thing called....
molar mass.....
calculate the molar mass of the Kr and then change it to grams...
its class 10th thing...not a rocket science......
or give me the full question .......

He's correct, ....the 10^23 cancelled out.

I know how to do it, it's my calculator giving me error when I ever I do the first conversion.

Is 3.485*10^-5 the ans?

I'm converting to grams so =144.97 grams

so you needed help with mathematics

Nope, calculator should have the answer in first place.

Stay here guys, I'm almost getting back to single replacement reactions.

I'm only getting 3 hours sleep today screw it I'm not sleeping.

@Talon help me wifey for the rest of the night everybody will get tired of me.

Take it easy on me guys I'm new to chemistry and remember we Arabs have 45IQ compared to Indo/Pak 115 .
