NASA pointed the Hubble Space Telescope at a very dark section of sky to see what might be found. The telescope revealed about 10,000 distant and never-before-seen galaxies. NASA would have to make observations of more than 10,000,000
other sections to study the rest of the sky. If every section of sky also looked out on 10,000 galaxies, about how many
galaxies would exist in the known universe?
100,000,000
1,000,000,000
10,000,000,000
100,000,000,000

well in order to answer this question you have to provide more information < 3

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.

its first and third is your answer i did the qustion the fourth isnt right
