How many hydrogen atoms are in 89.5 g of
C6H6 ?
Answer in units of atoms.

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.

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
