Answer:
Moles of TNT = 2.38 moles
Explanation:
First , calculate the molar mass of the compound TNT
The formula is : C7H5N3O6
How to calculate molar mass?
Molar mass : It is the mass of substance in grams which is present in 1 mole of the compound.It is calculated by:
Molar mass = Number of atoms x the atomic mass of the element
Atomic mass of the elements are given below :
C = 12.0107
H = 1.0079
N = 14.0067
O = 15.9994
Molar mass of C7H5N3O6 =
= (7 x C) + (5 x H) + (3 x N) + (6 x O)
= 7(12.0107) +5(1.0079) + 3(14.0067) + 6(15.9994)
Molar mass = 227 .13 gram/mole
Mole are calculated using the formula:

Given mass = 539.88 grams
Molar mass = 227.13 g/mole

= 2.3769
Moles = 2.38 moles

Answer:
Deforestation, increase wildlife extinction, ecosystem imbalances, soil erosion, migration and loss of species.
Explanation:
Global warming is warming the earth's surface temperature, which causes the changes in our ecosystem like deforestation, soil erosion, climate changes, migration and loss of species etc.
Global warming is caused by the 'Greenhouse effect', major gases are carbon dioxide(9-26%), methane(4-9%), water vapour(36-70%) ozone(3-7%) and nitrous oxide.
Global warming affects on the ocean include rising sea level, meiting glaciers, thermal expansion and ice sheets. It also cause the bird migration which carries high cost of predation and mortality.
