Solution : Given,
Density of nickel =
Number of nickel atoms =
Molar mass of nickel = 58.7 g/mole
First we have to calculate the moles of nickel.
As, atoms form 1 mole of nickel
So, atoms form
moles of nickel
The moles of nickel = 3.321 moles
Now we have to calculate the mass of nickel.
The mass of nickel = 194.94 g
Now we have to calculate the volume of nickel.
Therefore, the volume of the cube is,
Answer:
The volume of the gas is 2.80 L.
Explanation:
An ideal gas is a theoretical gas that is considered to be made up of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The Pressure (P) of a gas on the walls of the container that contains it, the Volume (V) it occupies, the Temperature (T) at which it is located and the amount of substance it contains (number of moles, n) are related from the equation known as Equation of State of Ideal Gases:
P*V = n*R*T
where R is the constant of ideal gases.
In this case:
- P= 2 atm
- V= ?
- n=0.223 moles
- R= 0.0821
- T=33 °C= 306 °K (being O°C= 273°K)
Replacing:
2 atm* V= 0.223 moles*0.0821 * 306 K
Solving:
V= 2.80 L
<u><em>The volume of the gas is 2.80 L.</em></u>
