Nitrogen gas is introduced into a large deflated plastic bag. no gas is allowed to escape, but as more and more nitrogen is added, the bag inflates to accommodate it. the pressure of the gas within the bag remains at 1 \rm atm and its temperature remains at room temperature (20.0^\ c. how many moles n have been introduced into the bag by the time its volume reaches 22.4 \rm l?

The ideal gas law states PV = nRT. This can be rearranged to:

n = PV / RT

Pressure = 1 atm

Volume = 1 L

T = 293 K

R = 0.0821 atm L / mol K

n = PV / RT = 0.0416 mol nitrogen

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the answer is 303.15 or 303
