30.06904
Explanation:
C3H4: Mass % C = 36.033 x 100 / 40.0641 = 89
Your answer would be C) of the scientists and ideas that came before him. he's saying that without them he wouldn't be where he is at now. he used there knowledge and became who he is today
Answer:
In one mole of NH₄Cl <em>6.022 × 10²³ atoms of N </em>are present.
Explanation:
Given data:
Number of atoms of N = ?
Number of moles of NH₄Cl = 1 mol
Solution:
First we have to calculate the number of atoms in NH₄Cl .
There is only 1 mole of N in 1 mole of NH₄Cl .
Now we will calculate the number of atoms of nitrogen in one mole of N by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole of N = 6.022 × 10²³ atoms of N
Thus in one mole of NH₄Cl 6.022 × 10²³ atoms of N are present.
