Answer:
P= 36.76atm
Explanation:
According to the adeal gas equation P = nRT/ V
n= 3.6 mol, T = 485K, V = 3.90L R = 0.0821Latm/molK
P= 3.6× 0.0821× 485 / 3.9
= 36.76atm
A= mass number = number of protons and neutrons in the nucleus
Z= number of electrons = number of protons
Given, number of neutrons= 30
Z = A - 30 = 70 - 30 = 40
Z = 40
