Question

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 6.35 g of carbon. How many grams of oxygen does it contain? Which law are you assuming in answering this question?

Answer 1

`8.467` grams of oxygen

Step-by-step explanation:

The law governing this problem is "The Law of Constant Composition "

As per this law, all compounds irrespective of their origin and source have the same composition and properties in their purest form

It is a simple proportion and ratio related problem.

`1.50` grams of carbon require
`2.0` grams of oxygen

`1.0` grams of carbon will require oxygen

`= (2)/(1.5)`

`6.35` grams of carbon will require oxygen

`(2)/(1.5)*6.35\\= 8.4666\\= 8.467`

Answer 2

It contain oxygen atom calculated below
6.35gC x 2.00gO/1.50gC
= 8.47g O
The law is that a sample of a pure substance is the same as any other sample of the pure substance no matter what the source is
