No, because electrons do not reside in the nucleus. But if you are wonder if the Number of electrons and protons effect the atom then yes, it does. You must have a equal number of electrons and protons but as for the stability of the atom, electrons won't mess the nucleus up.
Answer:
2.68 cm^3
Explanation:
Density= Mass/Volume
so...
8.96 g/cm^3 = 24.01 g/ V
and then u solve so it would be 2.68 cm ^3

Answer:
I think its alike.... Pretty sure actually
For conversion of kPa and atm, the relationship is 1 atm = 101.325 kPa. So for 20000 kPa, the atm number is 20000/101.325=197.4 atm.
Answer: The number of molecules of gas the flask contains is
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 2.50 L
n = number of moles = ?
R = gas constant =
T =temperature = 273K (STP)
According to Avogadro's law:
1 mole of gas at STP contains = molecules
Thus 0.112moles of gas at STP contains = molecules
The number of molecules of gas the flask contains is
