25cm3 of gas at 1 atm has a temperature of 20 degree celsis .
Andreas93 [3]

Answer:

1.28 atm

Explanation:

To solve this problem, you need to use the gas laws, more specifically the Combined Gas Law. It is P1V1/T1 = P2V2/T2. Simply plug your values in. But be careful! Make sure you convert your 20 degree C and 28 deg C to Kelvin, as that it the only temperature scale the Gas Laws work with. Upon plugging in your values, you get approximately 1.28 atm.

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
