Answer:
Mass = 57.05 g
Explanation:
Given data:
Volume of SO₂ = 20.0 L
Temperature = standard = 273 K
Pressure = standard = 1 atm
Mass of SO₂ = ?
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
n = PV/RT
n = 1 atm × 20.0 L / 0.0821 atm.L/ mol.K× 273 k
n = 20.0 / 22.41/mol
n = 0.89 mol
Mass of SO₂:
Mass = number of moles × molar mass
Mass = 0.89 mol × 64.1 g/mol
Mass = 57.05 g
It is better for the whales to go where the whales have the ability to dive longer and deeper to find cooler water.
Answers and Explanations:
Physical properties are characteristics of substances that can be seen without a change in its chemical composition.
Here, physical properties are:
- density
- color
- luster
- taste
- abundance
- source
I'm not completely sure what you mean by "source", but I'm going to assume you mean the substance's origin found in nature.
