D. released a connection to the pedal. disengage is the opposite of engage so by stopping the connection he’s doing the opposite of connecting it

The density of ammonia ( NH_3 ) at 273 K and 1.00 atm is 0.75 g/L.

Explanation:

Temperature of the gas = T = 273 k

Pressure exerted by the gas,P = 1.00 atm

Volume occupied by the gas = V

Number of moles of gas = n

PV=nRT (Ideal gas equation)

$PV=\frac{\text{Mass of ammonia gas}}{\text{Molar mass of the ammonia}}$

$\frac{P\times \text{Molar mass of ammonia}}{RT}=\frac{\text{Mass of ammonia gas}}{V}=\text{Density of the gas}$

Density of the gas:

$\frac{1 atm\times 17 g/mol}{0.0820 L atm\mol K\times 273 K}=0.75 g/L$

The density of ammonia ( NH_3 ) at 273 K and 1.00 atm is 0.75 g/L.
