At stp, 32.0 liters of o2 contains the same number of molecules as what element?

12.04x10^23

Explanation:

I mole of a substance contains 6.022x10^23

Here, Molar mass of O = 16u

And molar mass of 02 32u

And 32g of 02 = 1 mole of 02

Therefore 32g of 02 has molecules = 6.022x10^23

Since 1 molecule of 02 has 2 atoms

Therefore 32g of 02 has atoms=2*6.02x10*23

= 12.04x10^23

Therefore, any element that contains 8.60 × 10^23 molecules contain the same number of molecules as 32 litres of O2 at STP.

Explanation:

At STP(standard temperature and pressure)

The volume of 1 mole of gas is 22.4 litres.

Number of molecules in 1 mole of gas is = 6.022×10^23 molecules/mole

The number of moles of O2 in 32 litres at STP;

n = 32litres ÷ 22.4 litres/mole

n = 1.429 moles of O2.

The number of molecules of O2 in 32 litres at STP is;

N = 32/22.4 moles × 6.022×10^23 molecules/mole

N = 8.60 × 10^23 molecules.

Therefore, any element that contains 8.60 × 10^23 molecules contain the same number of molecules as 32 litres of O2 at STP.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
