Answer:

C. 22L

Step-by-step explanation:

STP is 273 K and 1 atm

Remember that R=0.0821 atm*L/mol*K

Put this into ideal gas law and solve for volume

PV=nRT → V=nRT/P

V=[(1mol)*(0.0821 atm*L/mol*K)*(273 K)]/(1 atm)

V=[22.4133 atm*L]/(1 atm)=22.4133 L

So the answer is 22 L

bagirrra123 [75]

Answer:

177 and 178

Step-by-step explanation:

First, the expression for the 2nd mile marker is x+1.

Now, you add x and x + 1 together to get 2x + 1

Next, make 2x + 1 equal to 355

Now subtract 1 and then divide by two on both sides to get x = 177.

This means that the first mile marker is 177 and the next is 178.
