QUESTION:
A compound of P and F was analyzed as follows: Heating 0.2324 g of the compound in a 378-cm3 container turned all of it to gas, which had a pressure of 97.3 mmHg at 77C. Then the gas was mixed with calcium chloride solution, which turned all of the F to 0.2631 g of CaF2. Determine the molecular formula of the compound
ANSWER:Step 1 of 7
According to ideal gas law, the number of moles can be calculated by the following formula.
........................(1)
P = pressure
V = Volume
n = Number of moles
R = Gas constant
T = Temperature.
