Hey there!
Molar mass ( NH4)2SO4 = 132.1395 g/mol
So:
1 mole ( NH4)2SO4 ---------------- 132.1395 g
moles (NH4)2SO4 ----------------- 3.30 g
moles (NH4)2SO4 = 3.30 * 1 / 132.1395
moles (NH4)2SO4 = 3.30 / 132.1395
=> 0.0250 moles of (NH4)2SO4

Sir William Herschel announced its discovery on 13 March 1781, expanding the known boundaries of the Solar System for the first time in history and making Uranus the first planet discovered with a telescope.
Answer:The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound, C5H10O2, exhibits strong, broad absorption across the 2500-3200 cm^1 region and an intense absorption at 1715 cm'^-1. Relative absorption intensity: (s)=strong, (m)-medium, (w) weak. What functional class(cs) docs the compound belong to List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm^1. The functional class(es) of thla compound is(are) alkane (List only if no other functional class applies.) alkene terminal alkyne internal alkyne arene alcohol ether amine aldehyde or ketone carboxylic acid ester nitr
