A sample of seaweed contains 1 liter of water and has 50 grams of salt dissolved in its cells. The seaweed is placed in a soluti
masha68 [24]

seaweed having 50 g  salt in 1 L  water. The bucket contains 150 g of salt in 2 L of water

amount of water present in bucket is twice to amount of water in weed

V¬_water bucket=2×V_water weed

At equilibrium, volume of water in weed is x and volume in bucket is y but concentration remain same as follows:

50 /x=150 /y\\ Y = 3 x

At equilibrium, weed loose z L from 1 L  water to bucket containing 2 L as follows:

(2 + z) = 3 (1-z)\\ (2 + z) = 3 – 3 z\\ Z = 0.25 L

Thus, Weed will loose 0.25 L of water

A 10.0-gram sample of H2O(l) at 23.0°C absorbs 209 joules of heat. What is the final temperature of the H2O(l) sample?(1) 5.0°C
Aliun [14]
The specific heat capacity of water is 4200J/(kg*℃). So when absorbs 209 joules, the water sample will increase 209/(4200*0.01)=5℃. So the final temperature of sample is 23+5=28℃.
