Answer:
The number of molecules is 3,01E23 of N2
Explanation:
We use the formula PV=nRT, and STP: 1 atm of pressure and 273 K of temperature.
PV=nRT ---> n=PV/RT
n= 1 atm x 11,2 l /0,082 l atm/ Kmol x 273K
n= 0, 5 mol
We use the number of Avogadro:
1 mol---------6, 02E23 molecules
0,5 mol----- x= (0,5 mol x6, 02E23 molecules)/ 1 mol = 3,01E23
I think it is a radiation poisoning
Q = 5637 J
C =4.814 J/KgºC
Temperature : 45.5ºC - 20.9º C = 24.6ºC
Q = m x C x T
5637 = m x 4.814 x 24.6
5637 = m x 118.4244
m = 5637 / 118.4244
m = 47.60 g
hope this helps!
Its much stronger than if something was not strong.
