<span>The ideal gas under STP is 22.4 L/mol. While the gas has a rule of P1V1/T1=P2V2/T2.
So the volume under 101 kPa and 273 K is 0.2*22.4=4.48 L.
So under 200 kPa and 400 K is 3.33 L. So the answer is B.</span>

Since it is stated that it is an ideal gas, we use the ideal gas equation to solve the volume of this gas sample. The ideal gas equation is expressed as:

PV = nRT
V = nRT / P
V = 0.200 (8.314) (400) / 200x10^3
V = 3.33 x 10^-3 m³ or 3.33L

Therefore, the correct answer is option B.

Total density of filled ball with nitrogen gas: $\frac{0.12G+0.6524g}{0.560L} = 1.3792g/L$

The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with nitrogen will not float in the air because total density of filled ball is greater than the density of an air. Density of the evacuated ball D = 0.214 g/L

Density of nitrogen gas = $d_4=1.165g/L$

Mass of the nitrogen gas : $1.165g/L \times 0.560L = 0.6524g$
