If a mineral sample has a mass of 10 g, how many grams of oxygen does it contain?

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?

If there are 40g oxygen in a 100g sample then in a 10g sample you would divide 40/100 by ten and get 4/10. So you would have 4g.

To determine the amount of oxygen in a 10 g sample with 40% oxygen, you can set up a proportion:

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.

To find out the amount of oxygen in a 10g sample, you can use the concept of proportions. Since the compound has 40% oxygen, it means that for every 100g of the compound, there are 40g 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.
