What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
Jmmartinez7906
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.

When scientists record the volume of a gas why do the also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
What are the two properties that determine the state of a substance?
gases have no shape,volume water has volume but no shape solids have shape and volume gases have the most intermolecular space solids have least inter molecular space <><><><><> Temperature and pressure.
How does temperature effect a volume of air?
Temperature is not directly tied to volume, its related to pressure. Increasing the temperature will increase the pressure--only if volume is held constant. That is were volume and temperature are related, through pressure. However, if you increase the volume it does not change the temperature.
How do you find out the volume when you have molecular weight and wt of compound?
Use the compounds density.
What did Charles find about volume and temperature?
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.

When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
What are the four variables in the ideal gas law?
Pressure, volume, temperature & the amount of gas.
What is a molecular scale for pressure volume effect?
volume scales as L3

When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
What are factors that affect gas pressure?
There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure.
What are the effects of temperature and volume of gas samples at constant pressure?
If the volume is constant, the density does not change with temperature. With increasing temperature there is still the same number of molecules confined to the same volume of space, so no difference in density.
If the temperature of a gas is decreased at a constant pressure what happens to its volume?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
What determines the temperature at which a refrigerant vaporizes?
pressure / temperature / volume /enthalpy
