Explanation:
The scale under her feet exerts an equal force but opposite in direction.
This principle aligns with Newton's third law of motion, which says that "for every action, there is an equal and opposite reaction."
As the girl’s weight presses down on the scale with a force of 42N, the scale responds with an equal upward force in the opposite direction.
The resulting net force is zero, which explains why her weight does not break the scale.

Response:
To convert 6 grams, divide it by the atomic mass of fluorine.
Explanation:
Number of moles = Mass / atomic mass of fluorine
Provided information:
Mass of fluorine = 6 g
How do we convert this into moles of fluorine?
Solution:
Number of moles = Mass / atomic mass of fluorine
Number of moles = 6 g/ 19 g/mol
Number of moles = 0.32 mol
Thus, to convert 6 g of fluorine to moles, we need to divide the mass by its atomic weight.
