Question

Guys please solve Q6.
​

Answer 1

Explanation:

1. one atom of silver is 108g

Mass = g/mol (mol = 6.023×10^-23)

Mass of one atom of silver

= 108/6.023×10^-23

= 1.794×10^-22

2.One molecule of water

= 2×Atomic mass of HYDROGEN + Atomic mass of OXYGEN

= 2(1) + 16

= 2+16

= 18

Answer 2

Answer:

(1) Mass is grams. So here it is given that the mass of silver atom is 108 g , which will be the given mass. Thus, Mass of atoms of silver is 108 g.

(2). The Formula Mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all the atoms represented in its formula. The number of atoms is an exact number; it does not affect the number of significant figures. The average mass of one H2O molecule is 18.02 amu.
