Answer 1

Answer:

1 We assume you are converting between moles Nitrogen and gram.

You can view more details on each measurement unit:

molecular weight of Nitrogen or grams

The molecular formula for Nitrogen is N.

The SI base unit for amount of substance is the mole.

1 mole is equal to 1 moles Nitrogen, or 14.0067 grams.

Note that rounding errors may occur, so always check the results.

2First things first; pull out your Periodic Table. Find the atomic weight (probably in the top left corner.) This Atomic weight is the weight of 1 mole of atoms of that kind. For instance look at N (Nitrogen), you will see the atomic mass is 14.00674 grams. So that means if you had 1 mole of nitrogen atoms, it would weight, 14.00674 grams.

So if you have a fraction of a mole, say for instance, just multiply * 14.00674 grams to obtain the weight, 7.00337 grams. (I used the equation below):

Fraction of a mole * Atomic weight = weight or mass you have

Now we have to get what fraction of a mole you have. To start, you need know that all a mole means is you have 6.022 x 1023 atoms of that type. So if I tell you I have a mole of nitrogen, then I have 6.022 x1023 nitrogen atoms. That ugly number is called Avogadro's Constant, NA. Scientist use NA just so they don't have to keep writing that long number over and over again.

To get the fraction of a mole you have, take the number of atoms you have, and divide it by 6.022 x 1023. (Use equation below):

Number of atoms you have / 6.022 x 1023 = Fraction of a mole

After you do that, plug it into the first above equation and that should give you your answer.
