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
