Figuring target package weights, with particulates

Example : Butter brickle ice cream; density of mix 1.1 kg/L; overrun in ice cream 100%; density of candy 0.748 kg/L; candy added at 9% by weight, (i.e. 9 kg to 100 kg final product)

In 100 kg final product, we have:

9 kg of candy (or 9 kg / 0.748 kg/L = 12.0 L)

91 kg of ice cream (or 91 kg / (1.1 kg/L / (100/100 + 1)) = 165.4 L)

So, 100 kg gives a yield of 12 + 165.4 = 177.4 L

1 L weighs 100 kg / 177.4 L = 564 grams 

(Note : In many cases, ice cream of different flavours is frozen to the same weight. As a result, overrun of actual ice cream in product varies.)
