Which statements correctly describe plastics? Select all that apply. Some plastics are produced by chemically breaking large molecules into multiple, different molecules. O some plastics are produced by chemically breaking large molecules into multiple, similar molecules. Some plastics are produced by chemically joining the same molecule to itself. Some plastics are produced by chemically joining different molecules in an alternating pattern

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.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
