The chemical formula of the compound produced from the reaction of the anion (a negatively charged ion) with formula of A⁻ᵃ and a cation (a positively charged ion) with formula B⁺ˣ can be written as,
BₐAₓ

The answers to the questions above:

Row 2, Column 2: Na⁺ and NO⁻³ : Na₃NO
Row 2, Column 3: Ca²⁺ and NO⁻³ : Ca₃(NO)₂
Row 2, Column 4: Fe³⁺ and NO⁻³ : Fe₃(NO)₃
This can be furthered reduced to: FeNO
Row 2, Column 5: NH⁴⁺ and NO⁻³ : (NH)₃(NO)₄
Row 2, Column 6: Sn⁴⁺ and NO⁻³ : Sn₃(NO)₄

For the third row anion, S₂⁻
Row 3, Column 2: Na⁺ and S₂⁻ : NaS₂
Row 3, Column 3: Ca²⁺ and S₂⁻ : CaS₄
Row 3, Column 4: Fe³⁺ and Si₂⁻ : FeS₆
Row 3, Column 5: NH⁴⁺ and S₂⁻ : NHS₈
Row 3, Column 6: Sn⁴⁺ and S₂⁻ : SnS₈

For Row 4 anion, PO₃⁻⁴
Row 4, Column 2: Na⁺ and PO₃⁻⁴: Na₄PO₃
Row 4, Column 3: Ca²⁺ and PO₃⁻⁴ : Ca₄(PO₃)₂
Row 4, Column 4: Fe³⁺ and PO₃⁻⁴ : Fe₄(PO₃)₃
Row 4, Column 5: NH⁺⁴ and PO₃⁻⁴ : (NH)₄(PO₃)₄
This can be further simplified into NHPO₃
Row 4, Column 6: Sn⁴⁺ and PO₃⁻⁴ : Sn₄(PO₃)₄
This can be further simplified into SnPO₃

For Row 5 anion, CO₂⁻³
Row 5, Column 2: Na⁺ and CO₂⁻³ : Na₃CO₂
Row 5, Column 3: Ca²⁺ and CO₂⁻³ : Ca₃(CO₂)₂
Row 5, Column 4: Fe³⁺ and CO₂⁻³ : Fe₃(CO₂)₃
this can be further simplified into FeCO₂
Row 5, Column 5: NH⁴⁺ and CO₂⁻³ : (NH)₃(CO₂)₄
Row 5, Column 6: Sn⁴⁺ and CO₂⁻³ : Sn₃(CO₂)₄

Answer from: Quest

the product of the pressure and volume is also constant

Answer from: Quest

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.
