The atomic number is underlined in blue and the atomic mass is underlined in red. The number of protons and electrons is equal to the atomic number. The neutrons is equal to the atomic mass minus atomic number. The group is the vertical column the element is located in (circled in greenish), while the period is the horizontal row (circles in orange).

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
Answer A
Hope that helps!
Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.
