Question

1) The volume of 3.011*10^(23) atoms of hydrogen gas at N.T.P. is ________.
2) the no. Of electrons present in 1 mole of Azide ion are
3) the no. Of water present in 90 grams of water are

Answer 1

A mole of hydrogen contain 6.02 ×10^23 atom show the volume occupied by hydrogen at ntp is 22. 4 litre

The number of electrons in azide ion is 22 . Nitrogen has seven electrons. There arethree nitrogens in the azide ion.

A mole of a compound is a number of grams equal to the atomic weight of a molecule of the compound, so for water we have 2 hydrogen atoms and one oxygen, so the atomic weight of water is 1+1+16=18, so a mole of water is 18 grams. We have 90g of water so we have 90/18 = 5 moles of water.
