Which of the following describes a chemical property of oxygen
Answer:
nah but ill take points tho
Explanation:
Atoms with the same number of protons but different masses are called Isotopes.
<h3>What are Isotopes?</h3>
An isotope is one of two or more chemical elements that exist in different forms. Varied isotopes of an element have the same atomic number and protons in their nuclei, giving them the same atomic weight. However, each elemental isotope has a different amount of neutrons, which changes its atomic weight.
isobars - Isobars are atoms (nuclides) of several chemical elements that have diverse chemical characteristics but share the same physical characteristics. So, we may define isobars as elements with the same mass number but a different atomic number.

Given data: <span>molar mass = 180.2 g/mol in 920.0 ml of water at 25 °c.
</span><span>the vapor pressure of pure water at 25 °c is 23.76 mm hg.
</span>Asked: <span>the vapor pressure of a solution made by dissolving 109 grams of glucose
</span><span>
Solution:
moles glucose = 109 g/ 180.2 g/mol=0.605
mass water = 920 mL x 1 g/mL = 920 g
moles water = 920 g/ 18.02 g/mol=51.1
mole fraction water = 51.1 / 51.1 + 0.605 =0.988
vapor pressure solution = 0.988 x 23.76 = 23.47 mm Hg</span>
