Charge # = protons - electons
Mass # = protons + neutrons
so that would be
3-3= charge#
3+4= mass#
Solution :
Molar mass of
is :
M = 6×12 + 6×1 g
M = 78 g
78 gram of
contains
molecules.
So, 89.5 gram of
contains :

Now, from the formula we can see that one molecule of
contains 2 hydrogen atom . So, number of hydrogen atom are :

Hence, this is the required solution.
If you are talking about chemistry, it's coefficient!
Quantitative means to count how many of something. The correct answer is B, It has two eyes. Hope this helps
Answer:
6813.7g
Explanation:
Calculate the mass
Let x be the mass
If 1 mol of Fe has a mass of 55.85 g
1 mol =55.85g
122mol= x
we have x= 122•55.85g=6813.7g
