Goyal Brothers Class-10 Mole Concept and Stoichiometry for ICSE Chemistry Ch-5 Page-80 Practice Problems-1 Answer 1 Number of molecules in 128g of sulphur dioxide gas.

Molecular mass of SO 2 64amu. So 64g 1 mole 128g 128 64 02 mole Now 1 mole of SO 2 contains 6 x 10 23 molecules 0 2 mole of SO 2 contains 0 2 x 6 x 10 23. The first step is to find the number of moles of the sulfur dioxide.

We have this formula mass over molar mass and this is equal to 007 moles of SO 2. Looking at the chemical equations we can see that initially the enthalpy is given for two moles then for one mole and 3 moles for the last equation. Use the equation 2 Al 3 Cl 2 — 2 AlCl 3.
