Calculate the number of moles of an ideal gas if it occupies 1750 dm3 under 125,000 Pa at a temperature of 127 C.
Phoenix [80]

Hey there!


* Converts 1750 dm³ in liters :


1 dm³ = 1 L so 1750 dm³ = 1750 liters



* Convertes 125,000 Pa in atm :


1 Pa = 9.86*10⁻⁶ atm so 9.86*10⁻⁶ / 125,000 => 1.233 atm


* Convertes 127ºC in K :


127 + 273.15 => 400.15 K


R = 0.082 atm.L/mol.K


Finally, it uses an equation of clapeyron :


p * V = n * R * T


1.233 * 1750 = n * 0.082 * 400.15


2157.75 = n * 32.8123


n = 2157.75 / 32.8123


n = 65.76 moles



hope this helps!

If 16 moles of al react with 3 moles of S8 how many moles of Al2 S3 will be formed
Gnom [1K]

Answer:

8 moles

Explanation:

Al reacts with S_8 to produce Al_2S_3 as

Al+S_8\rightarrow Al_2S_3

The balanced chemical equation is

16Al+3S_8\rightarrow 8Al_2S_3

In the reaction, 16 moles of Al react with 3 moles of S_8 to produce 8 moles of Al_2S_3.
