Acontainer holds 15.0 g of phosphorous gas at a pressure of 2.0 atm and a temperature of 20.0 celsius. what is the density of the gas?

2.57 g/l
12.3 g/l
180 g/l
0.40 g/l

Density of the gas is 2.57 g/L.

Explanation: Converting the mass of phosphorous gas into its moles using the formula:

Given mass of phosphorous gas = 15 g

Molar mass of phosphorous gas = 31 g/mol

Using above equation, we get

Using Ideal gas equation, which is:

Given:

P = 2 atm

   (Conversion Factor: )

n = 0.484 moles (Calculated above)

 (Gas Constant)

Putting all the values in above equation, we calculate the number of moles.

V = 5.818 L

Now, to calculate density, we use the formula:

Density = 2.57 g/L

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
