<span>I’ve answered this question before so if these are the choices to the question presented:

An oxygen atom double-bonded to a carbon atom, with a hydrogen atom single-bonded to the same carbon atom. </span><span>

<span>A hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain. </span>

<span>A carbon atom single-bonded between two other carbon atoms, with an oxygen atom double-bonded to the central carbon atom as well. </span>

<span>An oxygen atom single-bonded between two carbon atoms within a carbon chain. 


Then, the answer would be “a hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain.<span>”</span></span></span>

According to the law of constant composition, how many grams of oxygen does this isolated sample contain?
KatRina [158]

The Mass of oxygen in isolated sample is 8.6 g

<h3>What is the Law of Constant composition?</h3>

The law of constant composition states that pure samples of the same compound contain the same element in the same ratio by mass irrespective of the source from which the compound is obtained.

Considering the given ascorbic acid samples:

Laboratory sample contains 1.50 gg of carbon and 2.00 gg of oxygen

mass ratio of oxygen to carbon is 2 : 1.5

Isolated sample will contain 2/1.5 * 6.45 g of oxygen.

Mass of oxygen in isolated sample = 8.6 g

In conclusion, the mass of oxygen is determined from the mass ratio of oxygen and carbon in the compound.

Note that the complete question is given below:

A sample of ascorbic acid (vitamin C) is synthesized in the laboratory. It contains 1.50 g of carbon and 2.00 g of oxygen. Another sample of ascorbic acid isolated from citrus fruits contains 6.45 gg of carbon. According to the law of constant composition, how many grams of oxygen does this isolated sample contain?

Express the answer in grams to three significant figures.

8.47 g
