in problem three. How many? Crumbs off, Sally? Good. Do you need to make one little each off The following solution So first is 0.50 Mueller NSL Second is 2.0 Mueller, calcium chloride and C is 1.5 Moeller n a o h. So this question is taken from the topic preparing solution. So first we can understand what is mean by the majority. See, morality is simply the number off moles off salute. It is the number off malls off salute divided by the volume. All solution in later. And we know that the number off Smalls is simply moss our molecular months. So in case off part A that is 0.50 Mueller an initial and Israel So we we find in this case is the A mask. So morality is equal to majority is a cultural number off moles a number off more physical toe Mosque over molecular mosque in tow Volume off solution in leaders So volume off Solution in leader Okay volume All solution in later. So molecular mass off Initial is N S E. L is 58.5. Molecular mosque off NSL is 58.5. Cram, Permal and volume off solution in later is one letter because it is mentioned that you need to make one literate off the following solution. So volume is tickle toe one later. So that means malaria ity. We can put the value off polarity. So majority is equal to zero point 25 Moeller. So put all these value. So we get 0.25 physical toe mass. Our molecular mass is 58.5 into one later. So on solving we get masses 29.2 g. So in the next case, case number B 2.0 Moeller calcium chloride. So the molecular mass off calcium chloride is is 111 g per mole. So volume is again one liter. So McGarity is 2.0 is equal toe mass our molecular masses 111 in tow. Volume is one later. So on solving this we get moss off Calcium chloride, is it? Oh, Graham to 22 g and in case off party 1.5 Moeller Any which solution? So molecular mass off any, which is 40 cramp Permal. So morality is 1.5 physical to mask our molecular masses 40 and volume is again one later. So volume off all the solution is one letter that is mentioned in the question. So volume is one later. So on solving we get mass is equal to 60 g, so that means moss off sodium hydroxide is 60 g. So in the party, that is the answer in the party question that is, are 29 0.2 g in the part B 22 g and in the part c 60 g 60 graham in part C.
