IUPAC name. Chromium(IV) oxide, Chromium dioxide.
Answer:
x = 3/6.02 = 0.50.
Explanation:
1 mole of CO2 has 6.02 x 10^23 molecules of CO2.
Say x moles of CO2 has 3.0x10^23 molecules of CO2.
Therefore x = 3/6.02 = 0.50.
Answer:
V₂ = 2.64 mL
Explanation:
Given data:
Initial volume = 20 mL
Initial pressure = 1 atm
Initial temperature = 10°C (10 +273 = 283 K)
Final temperature = 100°C (100+273 = 373 K)
Final volume = ?
Final pressure = 10 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 1 atm. 20 mL . 373 K / 283 K. 10 atm
V₂ = 7460 mL.K.atm / 2830 K.atm
V₂ = 2.64 mL
