The factor in determining the average atomic mass of an element is:
B or 2 relative abundance of each isotope because the by looking at how many protons , electrons and neutrons the most isotope is of the element has relative abundance.
Answer:
Calibration curves are used to understand the instrumental response to an analyte, and to predict the concentration of analyte in a sample.

Answer:
2.52atm for sure
Explanation:
We know that:
P1= 2.80atm
T1= 400k
T2= 360k
And we want to find P2= ?
We have an equation: P1/T1 = P2/T2
Multiple both side by T2 to remove it
P2 = 2.52
At STP one mole of gas takes up 22.4L which means that the answer is B since there is 6.02×10²³ molecules in one mole of a substance.
