1. Dr. Bayul studies rock formations all over the world. She is working on a study of two rock formations. The information from the study is as follows:
• Rock A formed from liquid rock.
• Rock B formed from small pieces of rock in a different place.
• Rocks A and B formed at about the same time.
Are Rocks A and B the same or different types of rock?
The rocks are
a the same type because they both formed from rock material.
b the same type because they formed at the same time.
c different types because they formed in different ways.
d different types because they formed in different places.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

it is the most commonly accepted one

answer: i dont know the answer but this might
