Answer:
<em>it's broken down into carbon dioxide and water </em>
Explanation:
We can use the ideal gas law equation to find the number of moles;
PV = nRT
where P - pressure
V - volume - 56.2 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature
standard temperature is 273 K
and standard pressure - 101 325 Pa
we can rearrange the equation to find the number of moles
substituting the values in the equation
n = 2.51 mol
molar mass of Ar - 40 g/mol
mass of Ar in the sample - 2.51 mol x 40 g/mol = 100.4 g
Ionic compounds are uses ions but both uses nonmetal elements to form bonds
