The mole concept is related to everyday chemistry. For this exercise, you are going to calculate the number of molecules or atoms. Identify one food item, find out what elements or compounds are in this item. Explain how you would calculate the number of molecules or atoms of your interest. Respond others having a difficult time with calculation.

0:00 Hello.

00:01 So in this question we have to find out a food item select any food item and we have to find out the number of elements the elements which are present there and also the number of molecules in that particular food item.

00:23 So the food item that we can take we use in our daily life it is glue.

00:30 Glucose.

00:33 And the molecular formula of this glucose, it is c6h12o6 here.

00:44 And the molecular mass of this compound, it is, we know that c6h12 .o6, there are 12 multiplied by 6 plus 1 multiply by 12 plus an oxygen, it has the 16.

01:04 Multiply by 6.

01:06 So in total it will be 180 gram per mole here.

01:12 So now we have to calculate for calculation on the formula of mole.

01:18 Mole it is equal to mass upon molar mass.

01:25 Or this mole it is denoted as n and this is denoted as a small m and this is molecular mass or molecular weight.

01:35 That the 180 gram of glucose is equal to 1 mole of glucose right and if we are given the value of the mass then in that case we can calculate the mole so we know that the 1 for example 180 gram of glucose it will contain the 1 mole of glucose means if the 180 mass is it is given there and we know that the 180 is the molecular weight, it will come the one mole of glucose here.

02:15 And similarly, we can also find the mole with the value of the number, number of the atoms divided by the aveigardro number...
