Video TranscriptSo for question number 1: we have 2.81 grams of phosphorus penta chloride and we want a number of moles here. So 1 mole of phosphorus penta chloride, molar mass here is 208.5 grams, so this is 2.81 divided by 208.5. Gives me the 3 big geront 0135 moles of p c l 5 for my answered number 1 and for number 2. I have 4.19 moles of p c l, 51 mole, p c, l, 5 molar mass of 208.5 g. This would sakto 4.19 times 28.5 and that's 874 grams of p c. L, 5. Show
In this type of question it is important to define whether you are looking for a "mole" of atomic chlorine (one atom - #Cl#) or a mole of the normal form of the diatomic gas chlorine, #Cl_2#. For this problem I will stick with the pure atomic definition, that is, a single chlorine atom. The results can be halved to obtain the gas molecule version, if you like. #PCl_5# has 5 moles of Cl per compound mole. One mole of #PCl_5# has a molecular weight of #(208.5g)/"mole"#. Thus, #2.47g# is #2.47/208.5 = 0.01185# moles of #PCl_5#. With a 5:1 ratio of Cl to compound, that is: Chemistry Chakiera J. Follow • 2 Add comment
