Hydrocarbon P, hydrocarbon Q and additive R are three different compounds.
A manufacturer measures the masses shown when making four products for use as engine fuels.
| Product | Mass of P in kg | Mass of Q in kg | Mass of R in kg |
|---|---|---|---|
| W | 1000 | 0 | 0 |
| X | 700 | 250 | 50 |
| Y | 1400 | 500 | 100 |
| Z | 700 | 200 | 100 |
Explain why product W is not a formulation.
