If the pressure exerted by a gas at 25 degrees C in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

About n=6.765 * 10^-5 moles

Step-by-step explanation:

Using PV=nRT, you can start by plugging these numbers in.

25 degrees celsius is 298 degrees Kelvin.

3.81 * 0.044=n *R * 298

Dividing both sides by 298 and the universal gas constant, you get about:

n=6.765 * 10^-5 moles.

Hope this helps!

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
