Two gas-filled tanks have the same volume, temperature, and pressure. They are identical in every way except that one is filled
Tems11 [23]

Answer:

The tank with O₂ weighs more.

Explanation:

We can find the mass of gas using the ideal gas equation.

P.V=n.R.T=\frac{m}{M} .R.T\\m=\frac{P.V.M}{R.T}

Considering the pressure (P), volume (V), temperature (T) and ideal gas constant (R) are the same, we can establish that:

m ∝ M

The mass is directly proportional to the molar mass. The molar mass of O₂ (32 g/mol) is higher than the molar mass of N₂ (28 g/mol). Therefore, the tank with O₂ weighs more.

Lemur [1.5K]
The answer
the main formula is given by
Q=mSDT
 where m= mass
             s= specific heat
             DT= <span>change in temperature

so  Q =  50.89 x 1.8x 4.11 = 376.48</span>
