Transcript

00:01 Hello students, welcome here in this question we have some conversions are given.

00:06 So the first one is given as 125 mc per liter as caco3 of co2 is given.

00:22 So like this sub all are given in mz per liter so of co3.

00:29 So first of all, we had to calculate the number of merely equivalent weight.

00:35 So equivalent weight of this one, c .a.

00:41 Co3, is equal to 100 grams per mole is a molar mass divided by this one is ca plus 2 and minus.

00:54 So it is having equivalence to, that's why it is 50 grams is a equivalent weight of color.

01:01 Calcium carbonate.

01:02 And here it is calcium co2 is given.

01:06 So co2 molar mass is co2.

01:12 So equivalent weight for this one, equivalent weight is equal to.

01:18 So this one is 44 divided by 2.

01:23 So co2 minus it is present.

01:26 So that's why it is having the grams, it is 22 grams per.

01:31 Mole is an equivalent weight.

01:34 Now from this the number of moles, so here we will calculate a concentration of co2.

01:44 Co2 is equal to concentration of ca -co -3 multiplied by equivalent weight of co2 divided by equivalent weight of ca -c -a -c -c -o -3.

02:05 Co3.

02:05 Now the concentration of co3 is equal to, so number of equivalent weight co3 is equal to, here it is 125 m g per liter is given, so this one, and multiplied by equivalent weight of calcium, carbon oxide is 22 and this one is 50.

02:29 So the concentration of this one is 55 m g, per liter and another conversion is given so the same n 125 m z per liter as c c o 3 of calcium hydroxide okay now in calcium hydroxide so number merely equivalent weight of c aoh -h twice is equal to so so 74 is a molecular weight and this one is a number of equivalents.

03:09 So that is equal to o, here it is 37 grams per mole is a equivalent weight.

03:16 Now the concentration of caoh twice is equal to here the concentration of c .a .c .o .3 multiplied applied by equivalent weight of calcium hydroxide divided by that of calcium carbonate.

03:41 Now here it is equal to calcium, it is 125, mz per 1 .37 divided by this one is 50.

03:53 So then the concentration of cao -h whites is 92 .5 % percent.

03:59 M .g per liter.

04:02 Okay.

04:03 Now another one is here c.

04:09 125 mz per liter as c .a.

04:15 Co3 of h2, p .o4.

04:20 Now for h2, p .o4, equivalent is equal to for h2 so now it is a 97 is a molar mass for this one...
