What information does the percent composition of an atom in a molecule

1 answer:

4 0

The information that the percent composition of an atom in a molecule give is the The total mass that element contributes to a molecule. That is option C.

<h3>What is percent composition of an atom in a molecule?</h3>

The percent composition of an atom in a molecule is the total mass/amount of an element present in a molecule/compound to the molecular mass of the compound, multiplied by 100.

The mass of an atom is the amount of matter that is contained in that atom.

When you are calculating the percentage composition of an atom in a molecule this is to find out the mass of the atoms of the element that contributes to the given molecule.

How can the rate constant be determined from the rate law?

Vinil7 [7]

Answer:

B. The rate constant is the reaction rate divided by the concentration

terms.

Explanation:

The rate constant can be determined from the rate law because it is the reaction rate divided by the concentration terms. I hope I could help! :)

A chemist mixes 71.1 g of carbon tetrachloride with 65.4 g of isopropenylbenzene and 4.02 g of 2-ethyltoluene. Calculate the per

-Dominant- [34]

Answer:

% Carbon tetrachloride = 50.6 %

% isopropenylbenzene = 46.5 %

% 2-ethyltoluene = 2.9%

Explanation:

Step 1: Data given

A mixture contains:

71.1 grams of Carbon tetrachloride (CCl4)

65.4 grams of isopropenylbenzene (C9H10)

4.02 grams of 2-ethyltoluene (C9H12)

Step 2: Calculate total mass

Total mass = mass CCl4 + mass C9H10 + mass C9H12

Totam mass = 71.1g + 65.4g + 4.02g

Total mass = 140.52 grams

Step 3: Calculate % of each component:

% component = (mass component/ total mass) *100%

% Carbon tetrachloride = (71.1 / 140.52) *100 %

% Carbon tetrachloride = 50.6 %

% isopropenylbenzene = (65.4 / 140.52) *100%

% isopropenylbenzene = 46.5 %

% 2-ethyltoluene = (4.02/140.52) *100%

% 2-ethyltoluene = 2.9%

50.6% + 46.5% + 2.9% = 100%

Students asked to measure the temperature of a reaction beaker recorded the following temperatures. 103.7°C, 108.4°C, 105.8°C, 1

Nata [24]

There are two terms

a) accuracy : it relates to the exactness of an answer that how an answer is close to the actual answer or actual reading

So 104.6 is accurate

b) Precision : This is related to the closeness of different readings with each other

The first reading is 103.7 and the second one is 108.4 so the second reading is quite different from the first reading so it cannot be called as precised

Again 105.8 has good difference from the second reading hence again this is not precised

However the last reading 104.6 is quite near to 105.8 so 104.6 can be called as precise
