b)0.02 mole of sodium
c)1 molecule of water​

Answer 1

Answer:

(a) 12.01 (b)12.044×10²³ (c) 18grams

Explanation:

(a) mass of 1 atom mass of 100 atoms

12.01 1.201

(c) 1gram+1gram+16grams= 18grams

Because Water Contain 2 Hydrogen molecules And 1 Oxygen molecule

(b) Avagdro Number -6.022times×10²³

This Value =0.2 moles

Avgadro number÷Value number

6.022×10²³÷0.2

= 12.044×10²³
