Question

In a formula , W2 - W1 / W1 × 100 , W1 represents :

a) amount of water absorbed

b) final mass of raisins

c) inital mass of dry raisins

d) persentage of water absorbed ​

Answer 1

Answer:

d) percentage of water absorbed ​

Reason:

Let W1 be the weight of raisins before immersing them in water.

1]     W1=4.0 g. Let W2 be the weight of raisins after immersing in water for few hours.

2]    W2=7.0 g. Therefore, the weight of water absorbed by raisins is W2-W.

3]     W2-W1=3.0 g. The percentage of water absorbed by raisins = [(W2-W1)/W1]*100%             [(W2-W1)/W1]*100% =75 %

Hope it helps.......... :)
