A molecule has the empirical formula C4H6O. If its molecular weight is determined to be about 212 g/mol, what is the most likely
krok68 [10]

Answer:

The molecular formula is C12H18O3

Explanation:

Step 1: Data given

The empirical formula is C4H6O

Molecular weight is 212 g/mol

atomic mass of C = 12 g/mol

atomic mass of H = 1 g/mol

atomic mass of O = 16 g/mol

Step 2: Calculate the molar mass of the empirical formula

Molar mass = 4* 12 + 6*1 +16

Molar mass = 70 g/mol

Step 3: Calculate the molecular formula

We have to multiply the empirical formula by n

n = the molecular weight of the empirical formula / the molecular weight of the molecular formula

n = 70 /212 ≈ 3

We have to multiply the empirical formula by 3

3*(C4H6O- = C12H18O3

The molecular formula is C12H18O3

If 5. 0 grams of kcl is dissolved in 500 ml of water, what is the concentration of the resulting solution?
Lady_Fox [76]

If 5.0 grams of KCl is dissolved in 500 ml of water, the concentration of the resulting solution will be 0.134M.

<h3>How to calculate concentration?</h3>

The concentration of a solution can be calculated by using the following formula;

Molarity = no of moles ÷ volume

According to this question, 5.0 grams of KCl is dissolved in 500 ml of water. The concentration is calculated as follows:

no of moles of KCl = 5g ÷ 74.5g/mol = 0.067mol

Molarity = 0.067mol ÷ 0.5L = 0.134M

Therefore, if 5.0 grams of KCl is dissolved in 500 ml of water, the concentration of the resulting solution will be 0.134M.

Classify the definitions as that of an Arrhenius acid, an Arrhenius base, or that of a different type of acid or base. A substan
kifflom [539]

Answer:

A substance that can accept a hydrogen ion from another substance- a different type of base.

A substance that produces an excess of hydroxide ions (OH-) in aqueous solution- Arrhenius base

A substance that produces an excess of hydrogen ions (H+ ) in aqueous solution- Arrhenius acid

A substance that can donate a hydrogen ion to another substance.- a different type of acid.

Explanation:

Arrhenius defined an acid as any substance that produces hydrogen ion as its only positive ion when dissolved in water and a base as a substance which produces hydroxide ions as its only negative ion when dissolved in water.

This has informed the classification of definitions shown in the answer above.
