In covalent bonding, both atoms are trying to attract electrons--the same electrons. Thus, the electrons are shared tightly between the atoms.
The force of attraction that each atom exerts on the shared electrons is what holds the two atoms together.
The conversion factor to use in this case is:
charge / mass = 5.4 x 10^6 z / w
We are given that:
charge = 4.5 x 10^−15 z
Therefore the mass is calculated by combining the two
equations:
4.5 x 10^−15 z / mass = 5.4 x 10^6 z / w
<span>mass = 8.33 x 10^-22 w</span>
Hello There! ^_^
Your question: What is the pressure of a fixed volume of hydrogen gas at 38.8°C if it has a pressure of 1.36 atm at 15.0°C..?
Your answer: P1/ T1= P2/ T2
Change C to Kelvin
273+ C= K
38.3+ 273= 311K
15.0+ 273= 288K
2.38/ 288= P2/ 311.3
740.894= 288 (P2)
P2= 2.57 atm.
Thus, you got you answer!
Hope this helps!
Fluorine - 18.998 u
chromium - 51.996 u
tellurium - 127.6 u
dysprosium - 162.5 u
Moles pf mgcl2= 2,11/M mgcl2=2,11/95= 0,0222
Molarity=0,0222/1,5=0,0148 M.
I hope this is correct.
