Answer:
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
Explanation:
The pressure is determined by the definition of stress, which is the force exerted by the buggy on the martian surface divided by the contact area of the latter:
Where:
- Stress, measured in pascals.
- Force, measured in newtons.
- Area, measured in square meters.
The force is the weight of the buggy (40 N) and , the stress is now calculated:
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
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
