A plastic bag is weighed and then filled successively with two gases,X and Y.The following data are gathered:
Temperature: 0.0°C (273 K)
Pressure: 1.00 atmosphere
Mass of empty bag: 20.77 g
Mass of bag filled with gas X: 24.97 g
Mass of 1.12 liters of air at conditions given: 1.30 g
Volume of bag: 1.12 liter
Molar volume at STP: 22.4 liters
-The mass of 1.12 liters of gas Y is found to be 6.23 g.The density of gas Y is
A)10.6 g/L
B)5.56 g/L
C)15.6 g/L
D)0.200 g/L
E)0.180 g/L

The density of a substance is calculated by dividing its mass by its volume. For gas Y, the mass is given as 6.23 g and the volume is 1.12 liters. Therefore, the density of gas Y is $ \frac{6.23 \, \text{g}}{1.12 \, \text{L}} = 5.56 \, \text{g/L} $.
