Answer:
The weight changes, but his or her mass does not.
Explanation:
The true statement from the given choices about an astronaut traveling from planet to planet is that the weight changes but his or her mass does not.
This is due to the difference in acceleration due gravity from one planet to the other.
- Mass is the amount of matter present within a substance.
- Weight is the vertical force on a body due to its mass and acceleration due gravity
Gravity from one planet to the other differs significant and so is the weight.
Answer:

M=mol/L, 0.323M=mol/0.01325. Rework to solve for mol and bam! (I.e. times the two numbers)
V=84.0 mL = 84.0 cm³
m=609.0 g
p=m/v
p=609.0/84.0=7.25 g/cm³
