Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
a) In 100g of glucose;
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
Evolution would least likely be a cause of natural selection.
Natural selection has to do with the survival of the fittest. Therefore, adaptation, variation, and overpopulation all have an impact on natural selection - those who do not adapt to their new surroundings due to overpopulation or those whose bodies have not modified enough will not survive.
The answer is urticaria (also known as hives).
Atoms are the most basic units
Elements are specific types of atoms
Compounds are composed of more than one type of element and are held together by chemical bonds
