In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zo

oplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.

How many moles would there be in 100 g of glucose? In 500 g of glucose? SHOW WORK
vivado [14]

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
