Answer:

In living systems, diffusion of substances into and out of cells is mediated by the plasma membrane. Some materials diffuse readily through the membrane, but others are hindered, and their passage is only made possible by protein channels and carriers.

Wally fluoride is an imaginary gaseous
mihalych1998 [28]

Answer:

\rho =1.96\frac{g}{L}

Explanation:

Hello there!

In this case, since this imaginary gas can be modelled as an ideal gas, we can write:

PV=nRT

Which can be written in terms of density and molar mass as shown below:

\frac{P}{RT} =\frac{n}{V} \\\\\frac{P}{RT} =\frac{m}{MM*V}\\\\\frac{P*MM}{RT} =\frac{m}{V}=\rho

Thus, by computing the pressure in atmospheres, the resulting density would be:

\rho = \frac{165/760 atm * 314.2 g/mol}{0.08206\frac{atm*L}{mol*K}*425K} \\\\\rho =1.96\frac{g}{L}

Best regards!

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container un
guajiro [1.7K]

Answer:

1.18 moles of gas

Explanation:

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container until the pressure is 0.78 atm, how many moles of gas remain in the container?​

for the sealed rigid container, the pressure is directly proportional to the amount of gas

3.00moles/1.98  atm =  ? moles/0.78 atm

? = 3.00 X 0.78/1.98  =1.18 moles of gas
