Answer:
Final pressure of the gas remaining in the first container is 3.5 atm
Explanation:
Since it is given that temperature is constant , we can apply -
PV=constant , where
P = Pressure of the gas
V = Volume of the container in which the gas is contained
Initially,
For container 1 -
= 4 atm
= 6 L
Finally,
For container 2 -
= 3 atm
= 1 L
For container 1 -
= ?
= 6 L
∴ 
= 
+ 

∴ 4×6 = (
×6) +(3×1)
∴
= 3.5 atm

Answer:- 0.88
Solution:- Masses of silver and copper metals are given and we are asked to calculate the percentage of silver in the alloy.
mass percent of Ag = 
Mass of Ag = 17.6 g
mass of Cu = 2.40 g
mass of alloy = 17.6 g + 2.40 g = 20.0 g
Let's plug in the values in the formula:
mass percentage of Ag = 
mass percentage of Ag = 88%
So, the mass percentage of silver in sterling silver is 88% and in decimal form it is 0.88.
