A gas of 190 mL at a pressure of 74 atm can be expected to change its pressure when its volume changes to 30.0 mL. Express its new pressure in units of atmospheres.
Answers
Answer : The new pressure of the gas will be, 468.66 atm
Explanation :
Boyle's Law : This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
or,
where,
= initial pressure of the gas = 74 atm
= final pressure of the gas = ?
= initial volume of the gas = 190 ml
= final volume of the gas = 30 ml
Now we put all the given values in the above formula, we get the final or new pressure of the gas.
Therefore, the new pressure of the gas will be, 468.66 atm
Answer: The new pressure of the gas is 467 atm.
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the new pressure of the gas is 467 atm.

amu = 34.055 or 34.1
Explanation:
to calculate the average mass, first convert the percentages into decimals. Then, calculate the mass numbers. To get this number, multiply the decimal by the mass number for each isotope and, then add them together.
( 0.315 x 32 ) + (0.685 x 35 ) = 34.055

Answer: d. Its base at or near the ground.
Explanation:
Fog is a visible weather condition in which the tiny droplets of water present in the atmosphere come together and which forms a thick cloud which lies close to the surface of the ground (land) or above the sea surface. Fog cuts the visibility down to one kilometers, it makes it difficult to observe the things through it. The fog is influenced by several factors such as wind conditions, nearby water bodies, and topography.
Fog is a cloud that has its base at or near the ground. The answer is letter D. Fog results when atmospheric water vapor condenses to the extent that the new forms, water droplets or ice crystals, become visible. Saturation of the air and sufficient condensation nuclei are ordinarily prerequisites for the formation of fog. One of the great hazards associated with fog is a lack of visibility.

Answer:
8.46 liters of 0.123 NaOH contains 25.0 grams of NaOH.
Explanation:
Molar is defined as Moles/Liter. 0.123 M means there is 0.123 moles of NaOH per 1 liter. We are asked to determine how many milliliters of this concentration NaOH it would take to deliver 25.0 grams of NaOH.
Use the units to guide the calculation.
Remember that: Concentration x Volume = Moles
(0.123 moles/liter)*(V) = moles
We want 25.0 grams of NaOH. Let's convert that to moles using the molar mass of NaOH:
(25.0 grams NaOH)/(24.0 g/mole) = 1.04 moles NaOH.
Now we can write:
(0.123 moles/liter)*(V) = 1.04 moles NaOH
V = (1.04/0.123) Liters
V = 8.46 liters
