Question

Convert 0.0821L⋅atmmol⋅K into mL⋅Pag⋅K.

1000.0 mL = 1.000 L

101325 Pa = 1.000 atm

for this problem 1.00 mol = 22.4 g

Your final answer must be in scientific notation.

Answer 1

(0.0821 L•atm/(mol•K)) × (1,000.0/1.000 mL/L) = 82.1 mL•atm/(mol•K)

(82.1 mL•atm/(mol•K)) × (101,325/1.000 Pa/atm) = 83,187,825 mL•Pa/(mol•K)

(83,187,825 mL•Pa/(mol•K)) × (1.00/22.4 mol/g) = 371,374.21875 mL•Pa/(g•K)

Round this down to 3 significant digits and rewrite in scientific notation:

371,374.21875 mL•Pa/(g•K) ≈ 371,000 mL•Pa/(g•K)

… ≈ 3.71 × 10³ mL•Pa/(g•K)
