What is the value and units of the molar gas constant?
The value of the molar gas constant is approximately 8.314 J/(mol•K). It is a universal constant used in the ideal gas law equation to relate the pressure, volume, temperature, and amount of gas in a system.
What does molar volume mean for a gas?
Molar gas volume is the volume of ONE moel of gas. It only depends on the pressure and temperature, not on the kind of gas. Molar volume at standard temperature and standard pressure is always 22,4 Litres (for any gas)
A solution has a pH of 4.5 this solution is?
One such solution can be made by mixing 50 milliliters of 0.1 molar potassium hydrogen phthalate with 0.1 milliliter of 0.2 molar hydrochloric acid, then diluting this mixture to a total volume of 100 milliliters. This is from theHandbook of Chemistry and Physics, 66th Edition, page D-145. This is, of course, not the only correct answer to this question.
How is volume related to molarity?
molarity simply means molar concentration. To calculate molar concentration, c: c = n / V where c=molar concentration (moldm-3) n=number of moles V=volume(dm3) V can also be cm3 but it needed to be converted first to dm3.
What happens to volume when moles are halved?
The volume is 50 %; the molar volume is 22,414 L.
How do you prove that the molar heat capacity at the constant volume?
no be quiet
Why has a gas two values of molar heat capacities?
Gasses have two specific heat capacities because the boundary conditions can affect the number by up to 60%. Therefore, a number is given to each boundary condition: isobaric (constant pressure) or isochoric (constant volume). In an ideal gas, they differ by the quantity R (the gas constant - the same one you use in the ideal gas law): Cp = Cv + R where Cp is the isobaric molar heat capacity (specific heat) and Cv is the isochoric molar heat capacity.
What is molar specific heat of solid at constant volume?
This is the necessary heat to raise the temprataure of 1 mol with 1 kelvin, at constant volume.
Why we use two type of molar specific heat?
For gases, there is heat specific heat capacity under the assumption that the volume remains constant, and under the assumption that the pressure remains constant. The reason the values are different is that when heating up a gas, in the case of constant pressure it requires additional energy to expand the gas. For solids and liquids, "constant volume" isn't used, since it would require a huge pressure to maintain the constant volume.
How can one determine the number of moles in a substance based on its volume?
To determine the number of moles in a substance based on its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.
How can one determine the number of moles in a substance when given its volume?
To determine the number of moles in a substance when given its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.
How can one determine the number of moles present in a substance by utilizing its volume?
To determine the number of moles in a substance using its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). Molar volume is a constant value that depends on the substance being measured.
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
What is difference between partial molar volume and specific volume?
Partial molar volume is the volume occupied by one mole of a component in a mixture at constant temperature and pressure, while specific volume is the volume occupied by one unit mass of a substance. Partial molar volume takes into account the presence of other components in the mixture, while specific volume is unique to a single substance regardless of its surroundings.
How do you find molar volume?
You can find molar volume by dividing the volume of a gas by the number of moles of gas present. The equation to calculate molar volume is V = nRT/P, where V is volume, n is the number of moles, R is the ideal gas constant, T is temperature, and P is pressure.
What information would you need in order to convert molarity to percent by volume?
To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.
What is the density of 3 molar sodium hydroxide in grams per milliliter?
the molar mass of sodium hydroxide is 40g/mol mike
