in this problem, we have to determine the Mueller Mass off each other molecular compound, which is given in the problem in a molecular compound, the molar mass of a compound will be the some off the mullahs mass off all the molecules which represents in the compound. Looking at the first compound, which is C two, h five or H, we can see here that there are two molecules off. See the six molecules five plus one here, six molecules off H or hydrogen and one molecule off. These are the mullahs. Masses off each other molecules. Si at n poor. Now, using this formula as we discuss, we compute the molar mass off C two h five or H where we multiply the molar mass off. See by two on mama's off H by six on mama's off. You buy one. It gives us the final number as the mullahs mask off CTS. Five words as 46.7 g per mole in support, be one mole off, etc. In is composed off. One more off see one mole off edge and one mole off in adding the Mueller masses off each other. These three molecules we get the Mueller Mass off SCN as 27.3 g per mole to get the mullahs mass off CCL four. We can see here that there is one more off carbon or see on for most of chloride or seal in this compound. During the calculation, we get the mamas off CCL four as 1 53.81 g per mole.
