Actually, the answer Cu(NO3)2 is incorrect for cuprous nitrate. Cu(NO3)2 is in fact cupric nitrate. Cuprous nitrate is represented as CuNO3 alone.
CuF
Cuprous nitrtate is copper(I) nitrate. CuNO3. The copper is in oxidation state '1' The more usual form is cupric nitrate that is copper(II)nitrate. Cu(NO3)2 The copper is in oxidation state '2'. NB THe 'cuprous/cupric' comes the Latin name for copper , which is 'cuprum'.
The formula for cuprous sulfide is Cu2S. Copper (I) or cuprous has a +1 charge, whereas Sulfur has a charge of -2. Cu^(-1) + S^(-2) -> Cu2S (The subscript is 2)
Cu3PO4 Copper (I) Phosphate.
The chemical formula of calcium nitrate is Ca(NO3)2.
cuprous nitrate
Fifty years ago, when I got my chemistry degree, "cuprous nitrate" was the standard name for what is now called, using the Stock System, "copper(I) nitrate". Its formula is CuNO3.
Formula: Cu3As

The chemical formula of a nitrate is MeNO3 (Me is the metal).
The formula for cuprous sulfide is Cu2S. Copper (I) or cuprous has a +1 charge, whereas Sulfur has a charge of -2. Cu^(-1) + S^(-2) -> Cu2S (The subscript is 2)

The chemical formula for ferric nitrate/ iron nitrate is Fe(NO3)3.
The chemical formula of calcium nitrate is Ca(NO3)2.
The chemical formula of cupric nitrate is Cu(NO3)2.
The chemical formula of aluminium nitrate is Al(NO3)3.
