80.0 mL of oxygen gas was collected when the temperature was 20.0°C. How many milliliters will the oxygen occupy if the
temperature changes to 54.0°C?

A. 1200 mL
B. 216 mL
C. 71.7 ml
D. 89.3 mL
(Please show your work)

89.3 mL

Explanation:

First we convert 20.0 °C and 54.0 °C to K:

With the absolute temperatures we can solve this problem by using Charles' law:

Where in this case:

We input the data:

And solve for V₂:

hi,

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
