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:

Answer:
C10H22
Explanation:
Molecular Solids comprises of a Vander waal's force of attraction between the molecule. These forces are very weak when compared to ionic and covalent bond.
In Carbon, Carbon is not a molecule but an atom. One of it unique characteristics is that it forms bonds with other carbon atoms. This property is know as catenation. The bond between these carbon atoms is know as covalent bond.
Graphite is an allotrope of carbon. It exists as black , slippery, hexagonal crystals.The carbon atoms in graphite forms flat layers and are joined together by strong covalent bonds. Graphite can be used as lubricant in engines.
Gold (Au) is an element on the periodic table with atomic number 79 and a mass number 197. It exists as a metal. Most times Gold forms hydrogen bonds.
C10H22 is known as decane. It is the tenth compound formed in the series of alkane family( an organic unsaturated carbon chain family). Alkanes are aliphatic hydrocarbons. The forces of attraction between the alkane family are weak.In decane , their exists Vander waal's force which makes Decane C10H22 a Molecular Solid.
