Dawson decided he would be Dawson and play with a flammable gas. He needs to know how many moles of gas it takes to occupy 210 L

Montano1993 [528]

According to ideal gas equation, 0.5186 moles of gas are required to occupy 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

<h3>What is ideal gas equation?</h3>

The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.

Substituting the given values in the given equation, n= 5.4×210/8.314×263=0.5186 moles

Thus there are 0.5186 moles occupying 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

i have an unknown volume of gas at a pressure of 0.50 atm a temperature of 325 k. If i raise the pressure to 1.2 atm, decrease t

Ronch [10]

Assuming that the number of mols are constant for both conditions:
$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$
Now you plug in the given values. V_1 is the unknown.
$\frac{0.50 atm*V_1}{325K} = \frac{1.2 atm* 48 L}{230K}
$
Separate V_1
$V_1= \frac{1.2 atm* 48 L * 325K }{230K*0.50 atm }$
V= 162.782608696 L

There are 2 sig figs

V= 160 L
