Given the molarity of the solution is
.
The volume of the solution is 10.9/1000 L
Number of moles of HCl = Molarity * volume of the solution in L
Number of moles of HCl =*
Number of moles of HCl = 2.7 moles.
Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles
Answer:
A
Explanation:
this is because the electrons are attracted to the protons, the stronger the attraction and energy level the closer the electrons are to the nucleus. this moves them to a higher energy orbital. For example in a Bohr diagram.
1.3g Sn X 118.71g Sn/ 1 mole Sn= 154.32g Sn
I think the answer is <span>B. The sun's gravitational pull on Planet A is equal to its gravitational pull on Planet B because distance does not affect gravity.
