Asample of gas has a mass of 0.673g. its volume is 250.0ml at a temperature of 83 degrees c and a pressure of 747 torr. the sample is composed of which of the following gases?
(a) xe
(b)ar
(c)so3
(d)co2
(e)h2

Explanation:

Given data:

Mass of sample = 0.673 g

Volume = 250.0 mL (0.25 L)

Temperature = 83°C (273+83= 356 k)

Pressure = 747 torr (747/760 = 0.98 atm)

Gas type = ?

Solution:

PV = nRT

n = PV/RT

n = 0.98 atm× 0.25 L / 0.0821 atm. L/mol.K × 356 k

n = 0.245 / 29.23/mol

n = 0.01 mol

Number of moles = mass/ molar mass

Molar mass = 0.673 g /  0.01 mol

Molar mass = 67.3 g/mol

molar mass of  CO2 = 44 g/mol

molar mass of  H2 = 2.016 g/mol

molar mass of  SO3 = 80.066 g/mol

molar mass of  Ar = 40 g/mol

molar mass of  Xe = 131.3 g/mol

So non of these gases are present.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
