Answer #1

use dilution formula

M1*V1 = M2*V2

1---> is for stock solution

2---> is for diluted solution

Given:

M1 = 100 %

M2 = 15 %

V1 = 575 mL

use:

M1*V1 = M2*V2

V2 = (M1 * V1) / M2

V2 = (100*575)/15

V2 = 3833 mL

Volume of water added = V2 - V1

= 3833 mL - 575 mL

= 3258 mL

Dilution factor = V2/V1

= 3833 / 575

= 6.66

Answer:

Volume of water added = 3258 mL

Dilution factor = 6.66

    Fresh orange juice contains 12.0 wt% solid and the water, and concentrated orange juice contain 42.0 wt% solids. Initially a single evaporation process was used for the concentration, but volatile constituents of the juice escaped with the water, leaving the concentrate with a flat taste. The current process overcomes this problem by bypassing the evaporator with a fraction of the fresh juice. The juice that enters the evaporator is concentrated to 58 wt% solids, and the evaporator product stream is...
