I believe the answer is false.
Answer: D
Explanation:
I assume you meant .
- The atomic mass of potassium is 39.0983 g/mol.
- The atomic mass of sulfur is 32.065 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
So, the formula mass of potassium sulfate is 2(39.0983)+32.065+4(15.9994)=174.2592 g/mol.
So, 5.00 moles have a mass of (5.00)(174.2592), which is about <u>870 g</u>
2.1 L
P1V1 = P2V2
P1 = 3.5 atm
V1 = 4.2 L
P2 = 7.0 atm
V2 = ?
Solve for V2 —> V2 = P1V1/P2
V2 = (3.5 atm)(4.2 L) / (7.0 atm) = 2.1 L
Answer:
It is called: Dipole-Dipole Interaction.
