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
Our planet has so many different ecosystems in which species live in. Whether it is the rainforest or a desert region, it seems that almost any place on earth can be one in which species have learned to adapt to living there. In short, yes there is great diversity on this planet.
