Answer:
Hi AP Chemistry student. It seems this experiment is impossible. Sterling Silver cannot be separated so easily with this pathetic equipment. However, if one were to carry this experiment out, I would assume they would need to put the alloy in the graduated cylinder and then somehow filter the silver out through filter paper or Buchner funnel. taking the mass with a stir rod is also helpful for the mass percent calculation. I hope this helps you out, good luck in Mrs. Fischer's class :)

Answer:
378.25°C
Explanation:
Given data:
Number of moles of gas = 0.750 mol
Volume of gas = 35.9 L
Pressure of gas = 114 KPa (114/101 = 1.125 atm)
Temperature of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
now we will put the values.
T = PV/nR
T = 1.125 atm × 35.9 L /0.750 mol × 0.0821 atm.L/ mol.K
T = 40.3875/0.062/K
T = 651.4 K
Kelvin to °C:
651.4 K - 273.15 = 378.25°C

Hello!
Data:
F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²
We apply the data to the Resultant Force formula, we have:
I hope this helps. =)
