You need more information than that to determine the amount of oxygen or any other element in the mineral. Your question is the same kind as, "My car was in the rain today. How much did it rain?"

you need more info!

Sorry, there is 40% oxygen.

If the compound has 40% oxygen, that means there are 40g oxygen in 100 g sample. So how many g oxygen will be in a 10g sample?

40 g oxygen / 100 g sample = x g oxygen / 10 g sample

To solve for x, cross multiply:

40 g oxygen * 10 g sample = 100 g sample * x g oxygen

400 g oxygen = 100 g sample * x g oxygen

Now divide both sides of the equation by 100 g sample:

400 g oxygen / 100 g sample = x g oxygen

4 g oxygen = x g oxygen

Therefore, the 10 g sample contains 4 g of oxygen.

So you can set up a proportion:

\( \frac{40g}{100g} = \frac{x}{10g} \)

To solve for x (the amount of oxygen in a 10g sample), you can cross-multiply and then divide:

\( 40g \times 10g = 100g \times x \)

\( 400g = 100g \times x \)

Now divide both sides of the equation by 100g to solve for x:

\( x = \frac{400g}{100g} \)

\( x = 4g \)

Therefore, the 10g sample of the mineral contains 4 grams of oxygen.
