2.22~g/L

Explanation:

According to the ideal gas law equation:

pV = nRT

Let's express the number of moles in terms of mass and molar mass:

$pV = \frac{m}{M} RT$

Let's divide both sides by volume:

$p = \frac{m}{MV} RT$

Notice that:

$\frac{m}{V} = d$

So the equation becomes:

$p = \frac{dRT}{M}$

Expressing density:

$d = \frac{pM}{RT}$

Substituting the given values:

$d = \frac{2.569~atm\cdot 32.49~g/mol}{0.08206~\frac{L~atm}{mol~K}\cdot 458~K} = 2.22~g/L$

Option (A) is the correct answer.

Explanation:

In convection oven there is circulation of hot air. Hot air expands much faster as compared to cold air.

Therefore, this due to the increase in circulation of hot air the food will get cooked or baked at faster rate.

Thus, we can conclude that out of the given options, the key difference in convection oven and a regular oven is that it circulates the hot air.
