PLEASE HELP Convert 0.30 moles of nitrogen gas into liters of nitrogen gas if density of N2 is 1.16 g/ml.

Please help me show work as well!

7.24 Litres

Explanation:

Density of a substance can be calculated as follows;

Density (g/mL) = mass (g) ÷ volume (mL)

According to the given information, mole of N2 = 0.30moles, density = 1.16 g/ml.

Mole = mass ÷ molar mass

Therefore, mass = molar mass × mole

Molar mass of N2 = 28g/mol

Mass = 28 × 0.3

Mass = 8.4g

Volume = mass/density

Volume (L) = 8.4/1.16

Volume = 7.24 Litres

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
