In problem 6, determine the increasing order of molarity.
00:04
So this question is taken from the topic solution concentration.
00:09
And we know that the molarity is simply number of moles, number of moles of salute, divide by the volume of solution in liter.
00:25
So volume of solution in liter.
00:28
So we have given basically the mass.
00:30
So we first find out the number of moles by using this formula so number of moles is equal to given mass divided by the molecular mass and the molecular mass of nacel we can find out from the product table that is 23 for sodium and 35 .5 for chlorine which is 58 .5 gram per mole is the molecular mass of nacell so now in the part in the part a we we can first find out the number of moles of nacl.
01:08
So number of moles is equal to weight over molecular weight.
01:12
So which is 29 .2.
01:19
So 29 .2 upon 58 .5.
01:22
So on solving this we get 0 .5 moles.
01:27
So molarity, now we can define the molarity.
01:30
0 .5 moles divide by the volume is again 0 .50 liter.
01:35
So we get this value is 1 molar...
