Find the number of 1-foot cubes that fill the fish tank
<h3><u>Explanation;</u></h3>
Volume of a cuboid such as the fish tank is given by the product of length width and height;
Such that; Volume = length × width × height
Similarly, we can count the number of 1 foot cube that can fill the fish tank.
And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.
We can use the ideal gas law equation to find the volume occupied by the gas
PV = nRT
where
P - pressure - 1.33 atm x 101 325 Pa/atm = 134 762 Pa
V - volume
n - number of moles - 18.0 g / 4 g/mol = 4.5 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in Kelvin - 29 °C + 273 = 302 K
substituting these values in the equation
134 762 Pa x V = 4.5 mol x 8.314 Jmol⁻¹K⁻¹ x 302 K
V = 83.8 L
volume occupied by He is 83.8 L
