Answer: The molar mass of the gas is 31.6 g/mol
Explanation:
According to ideal gas equation:
P = pressure of gas = 3.0 atm
V = Volume of gas = 25.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Moles =
The molar mass of the gas is 31.6 g/mol
Answer
Suspension
Explanation
A suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation
Answer:
2
Explanation:
The sample has halved twice.
1/2 of 1/2 is 1/4, and 1/2 of 1 is 1/2.
The reaction of sodium sulfide with hydrogen sulfide can be shown as
Sodium hydroxide is completely reacting and thus act as limiting reactant
Thus, 2.31 g Na2S produced.
