Answer:
5.3⋅10 - 23 g
(-23 has to be small numbers above)
According to stoichiometry and molar mass concept, there are 55.34 g of oxygen in 152.21 grams of CO₂.
What is molar mass?Molar mass of a compound or a molecule is defined as the mass of the elements which are present in it.The molar mass is considered to be a bulk quantity not a molecular quantity. It is often an average of the of the masses at many instances.
The molecular mass and formula mass are used as synonym for the molar mass.It does not depend on the amount of substance which is present in the sample.It has units of gram/mole.
Molar masses of an element are given as relative atomic masses while that of compounds is the sum of relative atomic masses which are present in the compound.
According to stoichiometry , if 44 g of carbon dioxide has 16 g of oxygen then, 152.21 g of carbon dioxide will have 152.21×16/44=55.34 g.
Thus there are 55.34 g of oxygen in 152.21 g of CO₂.

The electron configuration of element Y ends in s?p4. What is
the symbol for the ion most commonly formed by this element?
a y2+
b y2-
с ү6+
d Y
This problem is providing us with the end of the electron configuration an element as s²p⁴ and asks for the most commonly formed ion. At the end, the answer is b Y²⁻.
Electron configurationIn chemistry, when analyzing electron configurations, one must first take into account how the energy levels must be filled with electrons.
Now, note the problem states that the electron configuration ends by s²p⁴, which means it is closer to complete the octet so it needs two electrons in order to do so, as it behaves as a nonmetal.
Therefore, the most commonly ion formed by this element is Y²⁻, because of the fact that it needs two electrons to complete the octet and thus become chemically stable and likely to bond with a metal.

[WILL MARK BRAINLIEST!!] Describe the relationship between molecular structure and the strength of electrostatic
forces between molecules. How does this impact boiling and melting points?
Answer:
increase the bonding strength between two or more molecules
hope this help
Explanation:
Boiling points and melting points
The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces.

Identify the solution that is likely to have the greatest concentration of H . Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices orange juice ammonia pure water bleach blood
From what we know, we can confirm that the solution that is likely to have the greatest concentration of H+ is orange juice.
This has to do with the effects of H+ in a substance. The presence of hydrogen ions causes the substance to be more acidic, and the higher the concentration the higher the acidity of the substance. Since orange juice is the only acidic solution listed, we can know it will have the highest concentration of H+ ions.
Therefore, due to its acidic nature, we can confirm that the solution that is likely to have the greatest concentration of H+ is orange juice.
