Question

Express the following in liters at STP:



6.62 x 10-3 moles HF

Answer 1

The volume of 6.62×10⁻³moles of HF at STP is 148.38×10⁻³ L

Step-by-step explanation:

Given data:

Number of moles of HF = 6.62×10⁻³ mol

Volume of HF in litter at STP = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Standard temperature = 273 K

Standard pressure = 1 atm

Now we will put the values in formula.

1 atm × V = 6.62×10⁻³mol ×0.0821 atm.L/ mol.K × 273 K

V = 6.62×10⁻³mol ×0.0821 atm.L/ mol.K × 273 K / 1 atm

V = 148.38×10⁻³ L

Thus, the volume of 6.62×10⁻³moles of HF at STP is 148.38×10⁻³ L.
