Answer:
Genetic disorders is an illness caused by abnormalities in genes or chromosomes.The cells of all mammals contain approximately the same amount of deoxyribonucleic acid (DNA).
Explanation:
Mammals are affected through an increase in the number of cells and not in their size.
Mass O = 1.187 - 1.054 = 0.133 g
<span>Moles O = 0.133 g / 16 g/mol = 0.00831 </span>
<span>Moles metal = 2 x 0.00831 = 0.0166 </span>
<span>Atomic mass metal = 1.054 g / 0.0166 = 63.4 g/mol </span>
<span>( this is the atomic mass of Cu) </span>
<span>so the metal oxide is Cu2O</span>
