Question

Find the final moisture percentage.
Batch 1: Mass of initial product 500 kg
solid content at beginning = 9.5%
solids present in starting material = 47.5kg
water present at start = 452.5 kg
Batch 2: Mass of initial product 500 kg
solid content at beginning = 8.3%
solids present in starting material = 41.5kg
water present at start = 458.5 kg
How do I find the final water content left in batch 2??
Please help I've been struggling with this question for days now
