Answer:

Explanation:
Hello,
In this case, Avogadro's relationship allows us to relate the moles and the volume of a gas at an initial condition and an a final one as shown below:

Thus, the volume that 0.00684 mol of neon the same pressure and temperature is computed below as required:

Best regards.
The amount of matter in an object is said to be its mass. The SI base unit of mass is kilograms i.e.
.
The mass of the object =
(given)
For converting lbs to kg:

So, 
Hence, the mass of
object in kilograms is
.
<span>Answer:
1170 ml is the final volume of the sample of gas, if the pressure and moles in the container is kept constant.</span>
