If the reaction occurs between Fe2S3(s) and H+ (aq) and the equation is properly balanced with the smallest whole-number coefficients, what is the sum of the coefficients for all reactants and products?
Fe2S3(s) + H+ (aq)

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.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

you didnt put any of the following

the maximum mass of nh3 is nh3 in grams
