Which of the following would double the pressure on a contained gas at constant temperature?
1 answer:
Answer: C. doubling the number of particles in the container
Explanation: According to the ideal gas equation:'
P= Pressure of the gas
V= Volume of the gas
n= number of moles
T= Temperature of the gas
R = gas constant
As the gas is contained in a container with fixed volume and temperature is also constant.
Therefore, the pressure will double when number of moles or number of particles double.

Answer:
m = 31.284 grams
Explanation:
Given that,
The dimension of a magnesium block is 2.00 cm x 3.00 cm x 3.00 cm.
The density of magnesium is, d = 1.738 g/cm³
We need to find the mass of the magnesium block. We know that the density of an object is given by its mass per unit its volume. So,
So, the mass of the block is 31.284 grams.
