Determine which of the following contains greatest mass of hydrogen: 1 mol of ch4, 0.6 mol of c6h6, or 0.4 mol of
c3h8.

1 mole of methane has the greatest mass of hydrogen.

Explanation:

To calculate the mass of hydrogen, we use the equation:

     .....(1)

In 1 mole of methane, 1 mole of carbon atom and 4 moles of hydrogen atoms are there.

Molar mass of hydrogen = 1 g/mol

Moles of hydrogen = 4 moles

Putting values in equation 1, we get:

The mass of hydrogen in 1 mole of is 4 g

In 1 mole of benzene, 6 moles of carbon atoms and 6 moles of hydrogen atoms are there.

So, in 0.6 moles of benzene, (6 × 0.6) = 3.6 moles of carbon atoms and (6 × 0.6) = 3.6 moles of hydrogen atoms are there.

Molar mass of hydrogen = 1 g/mol

Moles of hydrogen = 3.6 moles

Putting values in equation 1, we get:

The mass of hydrogen in 0.6 mole of is 3.6 g

In 1 mole of , 3 moles of carbon atom and 8 moles of hydrogen atoms are there.

So, in 0.4 moles of , (3 × 0.4) = 1.2 moles of carbon atoms and (8 × 0.4) = 3.2 moles of hydrogen atoms are there.

Molar mass of hydrogen = 1 g/mol

Moles of hydrogen = 3.2 moles

Putting values in equation 1, we get:

The mass of hydrogen in 0.4 mole of is 3.2 g

Hence, 1 mole of methane has the greatest mass of hydrogen.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

the answer to this question is 3.
