Determine the molar mass of each of the following gases: a.) 0.82g of a gas that occupies 470mL at 0C and 1.00 atm (STP). b.) 1.48g of a gas that occupies 1.45L at 0C and 760 mmHg (STP). c.) 1.48g of a gas that occupies 1.30L at 695 mmHg and 20.0C. d.) 2.8g of a gas that occupies 2.4L at 0.87 atm and 27C.
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
Calculate the rate constant for the reaction when the reactant concentration in a first-order reaction is given 7.30×10-2M after 15.0s and it is also reported 4.40×10-3M after 65.0s . ?
