1 mole of a gas at STP occupies volume = 22.4 L

And

1 mole of of an element has a mass = Gram molecular mass (if it is molecule and O2 at STP is a molecule O2) = 2 x (atomic mass) =2 x 16 = 32 g

Since 22.4 L at STP = 1 mole =32 g of O2.

Note:

Some gases are monoatomic (like He,Ar,Kr,Xe, etc) in these case 1 mole of gas ay STP will have mass equal to their gram atomic mass.

bazaltina [42]

Answer:

Impurities will be trapped in the crystals of the benzoic acid crystallized in this manner.

Explanation:

After benzoic acid is dissolved in hot water, it should have been allowed to cool gradually before it is transferred into an ice bath.

This gradual cooling will aid the separation of impurities so that when the vessel is now submerged in an ice bath, only pure benzoic acid is recrystalized.

If the vessel is immediately submerged into an ice bath, impurities will be trapped in the crystals of the benzoic acid.

maksim [4K]
<h3>Answer:</h3>

Protons

<h3>Explanation:</h3>
  • An atom is the smallest particle of an element that can take part in a chemical reaction.
  • All atoms of the same element are similar in that they have the same number of protons.
  • Atoms of the same elements may have a different number of electrons or neutrons but will always have the same number of protons.
  • Atoms of the same elements with a different number of neutrons are known as isotopes.
  • When neutral atoms gain or lose electron(s) they form charged atoms known as ions.
