If you increase the temperature of an object does it affect the volume?
Yes, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume.
How do you find out the molar mass of a gas given density temperature and pressure?
MolarMass = [density x gas constant x temperature(in kelvin)] / pressure (in atm)
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
The molar enthalpy of vaporization of benzene at its boiling point 353.25 K is 30.8 kJ mol-1 What is the molar internal energy change?
It should be 0 as internal energy is a function of temperature, i.e: U (T) At the boiling point, there is no change in temperature, and hence DU= 0
When two gases of a chemical reaction are both at the same temperature and pressure and they have the same molar volume what is their stoichiometric ratio in the chemical equation describing the reac?
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
How will molar conductivity vary with concentration or temperature?
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't

What are the 3 factors that affect how quickly diffusion occurs?
Relative molar mass, temperature, and concentration difference/gradient.
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)
What is the percent composing of calcium Ca in CaO?
It would seem that because calcium and oxygen are in equal molar ratio for this compound that it would be 50 percent. But that is incorrect, because they each have differing molar masses. Oxygen has a molar mass of 16.000 and calcium has a molar mass of 40.078. So calcium is 40.078/56.078, which is 71.47 percent.
How do you find out the molar mass of a gas given density temperature and pressure?
MolarMass = [density x gas constant x temperature(in kelvin)] / pressure (in atm)
Why is CS2 a liquid at room temperature whereas CO2 is a gas at room temperature?
CS2 has a higher molar mass than CO2
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
How many times faster helium diffuses than oxygen at room temperature calculate?
He molar mass = 4 g/molO2 molar mass = 32 g/mol Rate of diffusion is inversely related to the square root of the molar mass. √4 = 2 √32 = 5.7 5.7/2 = 2.8 So, He diffuses about 2.8 times faster than oxygen.
If the flask were not thoroughly wiped dry how would this affect the molar mass?
The presence of water or cleaning solution will dilute or taint whatever is put inside. This change will affect the overall chemical property of the solution, causing a false mass and volume reading.
The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the?
molar heat of fusion
How does the speed of sound through gas increase?
There are two reasons. those ARE TEMPERATURE AND MOLAR MASS.
