Hello students, let's begin with this question.
00:03
Here the chemical formula of this aspartame is given which is equals to c14h18n2o5 and here in the first part we have to find out its molar mass.
00:17
So molar mass is equals to 14 multiplied by the molar mass of carbon plus 18 multiplied by the molar mass of hydrogen plus 2 multiplied by the molar mass of the nitrogen plus 5 multiplied by the molar mass of the oxygen.
00:43
So this is equals to 14 multiplied by 12 .01 gram per mole plus 18 multiplied by 1 .01 gram per mole plus 2 multiplied by 14 gram per mole plus 5 multiplied by 16 gram per mole.
01:02
So here we get its molar mass.
01:04
So the molar mass of this aspartame comes to be this is equals to 294 .32 gram per mole.
01:15
Now in the next part here the mass of aspartame is given which is equals to this is equals to 1 mg and this is converted into gram.
01:28
So 1 mg is 0 .001 gram.
01:31
Then here we have to find out the its moles.
01:35
So here the formula used to find out the moles is equals to the given mass divided by the molar mass...
