An isotope contains 47 protons, 47 electrons, and 60 neutrons. What is the identity of the isotope?
2 answers:
Answer:
To find the identity of the isotope we must first calculate the mass number
Mass number (M) = A + Z
Where
A is the atomic number
Z is the neutron number
A = 47
Z = 60
M = 60 + 47 = 107
From the options above
The answer is option A

Answer:
volume of gas=101.94L
Explanation:
Suppose given gas follows the ideality nature of gas
PV=nRT
n=35.8/44mol=0.814 mol
P=0.197atm
T=27.5C=300.5K
R=0.0821atm/mol/K
after putting all value we get,
V=101.94L
volume of gas=101.94L
