Question

how much will 1kg fresh mushroom become if dried

Answer 1

When drying fresh mushrooms yourself , you end up to a 10 to 1 ratio : 10 Pounds ( 4.5 kg ) of fresh mushrooms equals 1 pound ( 450g ) of dried .

Answer 2

Answer:

1 kg fresh mushroom dried weight will be  $=1000 \frac{g}{10}=100 g$

Explanation:

The fresh weight of a substance is the weight of the substance with all water content.  But, the dry weight of the substance is generally lower than its fresh water, as it is the fresh weight of the substance minus it's water content.

The dry weight of the substance depends on the amount of water content of the substance. It depends on the freshness.  Generally, mushrooms have fresh weight : dry weight $=10 : 1$

So, weight of the dry mushroom $=1000 \frac{g}{10}=100 g$
