Answer : The volume of 1 mole of
and
gases are the same.
Solution: Given,
Moles of
= 1 mole
Moles of
= 1 mole
Moles of
= 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of
are more than the moles of
and
. So, the volume of
will be more.
And the moles of
and
are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of
and
gases are the same.
Answer: The answer is 162g.
Explanation: To calculate the mass of a molecule, you have to find the molar mass of each element of the molecule.
Molar mass of C = 12g/mol
Molar mass of H = 1g/mol
Molar mass of O = 16g/mol
Molar mass of S = 32g/mol
From the allicin's formula, there are:
6 C = 6.12 = 72
10 H = 10.1 = 10
1 O = 1.16 = 16
2 S = 2.32 = 64
Adding them up:
C6H10OS2 = 72+10+16+64 = 162g/mol.
As it is requested 1 mol of allicin, it has 162g.
