Answer: The pressure inside the cylinder will be 1.5 atm. The pressure can be calculated using the Ideal Gas Equation which relates the pressure, volume, temperature, and amount of gas to each other.
Further Explanation
The Ideal Gas Equation is:
where:
P - pressure (in atm)
V - volume (in L)
n - amount of gas (in moles)
R - universal gas constant
T - temperature (in K)
In the problem, we are given the values:
P = ?
V = 10.0 L (3 significant figures)
n = 0.60 moles ( 2 significant figures)
T = 35.0 degrees Celsius (3 significant figures)
We need to convert the temperature to Kelvin before we can use the Ideal Gas Equation. The formula to convert from degree Celsius to Kelvin is:
Therefore, for this problem,
Solving for P using the Ideal Gas Equation:
The least number of significant figures is 2, therefore, the final answer must have only 2 significant figures.

Explanation:
Given parameters:
Atomic mass of Radium = 226
Mass of Radium = 497.2g
Unknown:
Number of moles = ?
Solution:
To solve this problem, we use the expression below:
Number of moles =
The molar mass of the radium = 226g/mol
So;
Number of moles = = 2.2moles
