Calculate the mass percent composition of nitrogen in co(nh2)2.

Answer : The percent composition of nitrogen in is, 46.7 %

Explanation : Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

Molar mass of N = 14 g/mole

First we have to calculate the molar mass of .

Molar mass of glucose =

Now we have to calculate the mass percent composition of nitrogen in .  

As we now that there are 1 number of carbon atom, 4 number of hydrogen atoms, 1 number of oxygen atom and 2 number of nitrogen atoms.

The mass of nitrogen =

Formula used :

Now put all the given values in this formula, we get:

Therefore, the percent composition of nitrogen in is, 46.7 %

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
