What is the amount of matter in an object.

A mass
B volume
C Density

Option A

Explanation:

The answer is "mass" or option A. It's not option B because volume is the amount of space in a object which is not what the question is asking for. It's also not option C because density goes hand in hand with volume measuring how much space a object takes up, and also density is mass per volume. Leaving only option A, therefore it is your answer.

Hope this helps.

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
