Answer:
it has a fixed volume it can also be compressed
Explanation:
a gases molecules don't move slow because they are not solid and are not compacted.
a gas does not have a fixed shape because there is nothing to hold its shape
Answer:
A the pressure is changed to 0.8
Explanation:
Boyles gas law
Given the mass percentage of HCl solution = 15.00 %
This means that 15.00 g HCl is present in 100 g solution
Moles of HCl = 
Density of the solution = 1.075 g/mL
Calculating the volume of solution from density and mass:

Converting volume from mL to L:

Calculating the molarity of HCl solution from moles and volume:
