10 gram of each of the following is taken which contain more number of atoms(a) Ethane(b) Ethene(c) Ethyne(d) All same​

To determine which contains more number of atoms, we need to calculate the number of moles in each substance. The number of moles is given by the formula:

Number of moles = mass / molar mass

The molar mass of ethane (C2H6) is approximately 30 g/mol, of ethene (C2H4) is approximately 28 g/mol, and of ethyne (C2H2) is approximately 26 g/mol.

For ethane: Number of moles = 10 g / 30 g/mol = 0.33 mol

For ethene: Number of moles = 10 g / 28 g/mol = 0.36 mol

For ethyne: Number of moles = 10 g / 26 g/mol = 0.38 mol

The number of atoms in a mole of a substance is given by Avogadro's number, which is approximately 6.022 x 10^23. Therefore, the substance with the most moles will have the most atoms.

So, Ethyne (C2H2) has more number of atoms.
