Answer:
C₃H₆ propene
Explanation:
Find the chemical formula by adding all the carbon and then all the hydrogen together.
A chemical reaction of exothermic kind releases energy in the form of heat and light.
We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.
We are required to find number of grams of reactant that has been consumed
It is also given that 880J of energy is released
Hence, grams of reactants consumed is 880/27.4gm

Explanation:
The given data is as follows.
Mass = 27.9 g/mol
As we know that according to Avogadro's number there are
atom present in 1 mole. Therefore, weight of 1 atom will be as follows.
1 atoms weight =
In a diamond cubic cell, the number of atoms are 8. So, n = 8 for diamond cubic cell.
Therefore, total weight of atoms in a unit cell will be as follows.
= 
= 
Now, we will calculate the volume of a lattice with lattice constant 'a' (cubic diamond) as follows.
= 
= 
=
Formula to calculate density of diamond cell is as follows.
Density = 
= 
= 2918.1 
or, = 0.0029 g/cc (as 1
)
Thus, we can conclude that density of given semiconductor in grams/cc is 0.0029 g/cc.
