Answer:
centroid- the point of concurrency of the <em>medians.</em>
<em />
orthocenter- the point of concurrency of the <em>altitudes.</em>
<em />
circumcenter- the point of concurrency of the <em>perpendicular bisectors.</em>
<em />
hope this helps :)
1/4 is equal to 0.25. so you can multiply 0.25 and 268 to get your answer of 67
For question 2 it is 15
Because: 4 time 6 is 24 and then you minus 9 which is 15
So there you have it the answer is 15

We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:
PV = nRT
Molar volume can be obtained from the equation by V/n.
V/n = RT/P
Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>
