30 POINTS TO WHOEVER HELP ME PLEASE Given the equation
MgCO3(s) + H2SO4(aq) ==> MgSO4(aq) + H2O(l) +CO2(g)
What mass of magnesium carbonate is needed to make 6 dm3 of carbon dioxide at rtp?
[Ar's: Mg = 24, C = 12, O = 16, H =1 and S = 32]

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

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.
