Answer:
For pure substances, the mass and volume will always be the same or will always change the same way because all substance are the same throughout.
While for mixtures, you can have varying amount of each component therefore mass and volume will not change the same way for substances

Answer:
<em><u>Mass (kg) × Acceleration (m/s²) = Force (N)</u></em>
Answer:
P = 0.979 atm
Explanation:
Given data:
Number of moles of methane = 40.8 mol
Volume of container = 1020 L
Temperature = 298 K
Pressure of gas =?
Solution:
According to ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
Now we will put the values,
P = nRT/V
P = 40.8 mol × 0.0821 atm.L/mol.K × 298 K / 1020 L
P = 998.2 atm /1020
P = 0.979 atm
Answer:
Energy
