RA=RWxRLxRHxRM

RA	:	Room air amount	[g]
RW	:	Room width	[m]
RL	:	Room length	[m]
RH	:	Room height	[m]
RM	:	Room air mass (1293)	[g/m3]

FA=RAxFC/(1-FC)

FA	:	Formaldehyde ammount	[g]
FC	:	Formaldehyde concentration	[-]

AA＝(FA/FM)xAMxAR

AA	:	Ammonia amount	[g]
FM	:	Formaldehyde mass (30)	[g/mol]
AM	:	Ammonia mass (17)	[g/mol]
AR	:	Ammonia/Formaldehide ratio (4/6=0.667)	[-]
