Chapter 5, Problem 57P(choose chapter or problem)
A compound of P and F was analyzed as follows: Heating 0.2324 g of the compound in a 378-\(\mathrm{cm}^{3}\) container turned all of it to gas, which had a pressure of 97.3 mmHg at 77°C. Then the gas was mixed with calcium chloride solution, which turned all of the F to 0.2631 g of \(\mathrm{CaF}_{2}\). Determine the molecular formula of the compound.

QUESTION:
A compound of P and F was analyzed as follows: Heating 0.2324 g of the compound in a 378-\(\mathrm{cm}^{3}\) container turned all of it to gas, which had a pressure of 97.3 mmHg at 77°C. Then the gas was mixed with calcium chloride solution, which turned all of the F to 0.2631 g of \(\mathrm{CaF}_{2}\). Determine the molecular formula of the compound.
ANSWER:Step 1 of 5
The goal of the problem is to find the molecular formula of the compound.
Given:
Mass of compound = 0.2324 g
P = 97.3 mmHg
T = 77°C =
Mass of F in \(CaF_2\) = 0.2631
V = 378 \(cm^3\)
