A student is required to prepare an orange paint by mixing only the primary paints red and yellow. The school uses a standard colour wheel in which the hue angle for pure red is 0°, pure yellow is 60°, and the hue angle of a mixed colour is determined by the linear proportion of the two primary colours used. The target orange colour has a hue angle of 45°. The student must prepare 250 ml of this orange mixture. The densities of the paints are: red paint = 1.05 g ml⁻¹, yellow paint = 1.02 g ml⁻¹. Answer the following:

Question Parts

( a )
Determine the ratio of red to yellow paint (by volume) required to obtain a hue angle of 45°.
( b )
Using the ratio from part (a), calculate the volume of red paint and the volume of yellow paint needed to prepare exactly 250 ml of the orange mixture.
( c )
If the densities given above are used, compute the mass of red paint, the mass of yellow paint and the total mass of the mixture. Also, state two possible sources of error that could affect the final colour of the mixture.
