there would be 3.752*10^24 atoms in 100 grams of CH4
Steps:
CH4: 12.01+4(1.01)=16.05
100g/16.05 mol mass=6.23g/mol
6.23*6.02*10^23=3.75*10^24
Answer:
Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus
Explanation: I hope this helps!!!!!
The answer is B. The chlorine has 7 electrons at the outer shell. So it will gain one electron to become stable when forms a chloride ion. And the gained electron will stay at the outer shell. So the radius becomes larger.
