A2.37 l balloon contains .115 mol of xenon gas, xe(g), at a pressure of 954 torr. what is the temperature, in kelvin, of the xe in the balloon? express the answer using 3 significant figures.
What helps me to balance equations is to list the elements i have on each side of the equation, and use tally marks to see what I have and don't have. Then when I'm done balancing, I tally again to make sure everything matches up.
On the left side, you have 1 Al, and 2 O. On the right side, 1 Al and 3 O.
In order for the equation to balance, you need to place a 2 in front of the AlO on the right side. This would make the Al have 2 atoms and the O have six. On the left side, you need to place a 2 in front of the Al and a 3 in front of the O, making it six. Left side: 2 Al's 6 O's. Right side: 2 Al's and 6 O's. Matches!
109/8.56=12.7
50+12.7
V=62.7
Mass= Volume x Density so i divided the mass and density to get the volume. and afterwards i would just add it to the mass to get my final answer
Answer:
<h2>1.54 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question we have

We have the final answer as
<h3>1.54 mL</h3>
Hope this helps you
