Answer: 1g of formaldehyde
Explanation:
Molar Mass of benzene (C6H6) = (12x6) + (6x1) = 78g/mol
1mole(78g) of benzene contains 6.02x10^23 molecules.
1g of benzene with contain = (6.02x10^23) /78 = 7.72x10^21 molecules
Molar Mass of formaldehyde (CH2O) = 12 +2+16 = 30g/mol
1mole (30g) of formaldehyde contains 6.02x10^23 molecules.
1g of formaldehyde will contain = (6.02x10^23) /30 = 2.01x10^22 molecules
Molar Mass of TNT(C7H5N3O6) = (12x7)+(5x1)+(14x3)+(16x6) = 227g/mol
1mole(227g) of TNT contains 6.02x10^23 molecules.
1g of TNT will contain = (6.02x10^23)/227 = 2.65x10^21 molecules
Molar Mass of naphthalene (C10H8) = (12x10) +8 =128g/mol
1mole(128g) of naphthalene contains 6.02x10^23 molecules.
1g of naphthalene will contain = (6.02x10^23)/128 = 4.7x10^21 molecules
Molar Mass of glucose(C6H12O6) = (12x6) + 12 +(16x6) = 180g/mol
1mole(180g) of glucose contains 6.02x10^23 molecules.
1g of glucose will contain = (6.02x10^23)/180 = 3.34x10^21 molecules
Therefore, 1g of each of the compound contains the following:
Benzene = 7.72x10^21 molecules
Formaldehyde = 2.01x10^22 molecules
TNT = 2.65x10^21 molecules
Naphthalene = 4.7x10^21 molecules
Glucose = 3.34x10^21 molecules
From the above, we see clearly that formaldehyde has the largest number of molecules
