How many grams of MgO are produced when 64.0 grams of 02 react completely with Mg? 2Mg+ 02= 2MgO

law of conservation of matter

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.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

thats how its supposed to be
