The first one is the answer
isotopes of an atom have different number of neutrons . the number of protons are not different in isotopes of an atom
14 uranium atoms in pure uranium
They usually get it from an old well they dug up and have a pump and strainer that go to their house.
The molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. is 5.23 gram.
<h3>What is an Ideal Gas ?</h3>
An Ideal Gas is a law for ideal gas which states that the product of Pressure and Volume is equal to the product of the moles of sample, universal gas constant and temperature.
PV = nRT
The given data in the question is
Pressure = 0.92 atm
Volume = 1.6 l
Temperature = 287 K
0.92 * 1.6 = n * 287 * 0.082
n = 0.06 moles
0.06 = 0.314 / molecular weight
molecular weight = 0.314/0.06
Molecular weight = 5.23 gm
Molar mass = 5.23 gm.
The temperature and pressure conditions at which the gas behaves like an ideal gas is 273 K and 1 atm.

<span>Although the molecules have similar electron domains, this doesn't mean they will have the same molecular shapes. This is because they differ in the number of nonbonding domains. The nonbonding domains play a vital role in how the shape of the molecule will turn out.</span>
