Using the ideal gas law, calculate M and identify the unknown. Give its name and draw its structure. ?? = ??? = (?/?)?T

what must be held constant in order to use Avogadros Law?

using Ideal gas law. volume =) TOL Temperature => 273k Pressure = 1 atm moles =>> ?

(please type answer no write by hend)

In case of Ideal Gas law, PV=nRT, what volume in Liters would 3.50 moles of Oxugen Gas , O2, occupy R= 0.0821  T=273K P=1 atm

Complete the following statements: At constant volume and number of moles, the pressure of an ideal gas ____ as the temperature decreases according to ___ .  At constant temperature and number of moles, the volume of an ideal gas ___ as the pressure decreases according to ___ .  At constant temperature and pressure, the volume of an ideal gas ___ as the number of gas atoms of molecules increases according to ___ .          5.) Calculate the temperature in C when 2.50 moles of argon occupy 25.0 L at 1.20 atm. Write the ideal gas equation and give the units for each term.         6.) A sample of oxygen gas occupies a volume of 400 mL at 50oC and 250 mmHg of pressure. What will its volume be at STP?           7.) 0.360 g of a diatomic gas occupies 125.0 mL at 23.0oC and 750. Torr. What is the molar mass of the gas? What diatomic gas is it?               8.) Acetylene (C2H2) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). 8.64 L of gaseous acetylene (C2H2) is burned…
