A sample of a mixture of salt and sugar has a total mass of 0.8920 g. If the sample contains 0.0982 g of salt, what percent of the sample is sugar?

89%

Explanation:

The computation of the sample percentage is sugar is shown below:

As we know that

The mass of the total sample mixture is

= Mass of salt + mass of sugar

= 0.8920

And, the mass of salt is 0.0982 g

So, the mass of sugar is

= 0.8920 - 0.0982

= 0.7938 g

Now the percentage of the sample is sugar is

= 0.7938 ÷ 0.8920

= 89%

if you mean hydrogen and oxygen then water is the product
