Question

Find the density of a gas at STP if it’s molar mass is 112g/mol

Answer 1

The density of a gas at STP can be calculated using the formula Density = Mass/Volume. Given that the molar mass of the gas is 112 g/mol and the volume at STP is 22.4 L/mol, the density of the gas is 5 g/L.

Step-by-step explanation:

The density of a gas at STP can be calculated using the formula Density = Mass/Volume. At STP, the volume of a gas is 22.4 L/mol. Given that the molar mass of the gas is 112 g/mol, we can substitute the values into the formula to find the density:

Density = Molar Mass / Molar Volume

Density = 112 g/mol / 22.4 L/mol = 5 g/L

Therefore, the density of the gas at STP is 5 g/L.

Answer 2

D= 5 g/L

Step-by-step explanation:

M= D x Vm

M is the molar mass = 112g/mol

D is the density

Vm is the molar volume whuch is 22.4L at STP

now substitute;

112 = D x 22.4

D= 112\22.4

D= 5 g/L
