How many moles are in 68.5 liters of oxygen gas at STP?

1 answer:

5 0

At STP, 1 mol of gas occupies 22.4 L.
mol O2 = 68.5 L * 1 mol/22.4 = 3.06 mol
The answer is that there are 3.06 mol of oxygen gas at STP.

Consider the equation for the formation of water.

Juli2301 [7.4K]

The theoretical yield is 160 g H₂O.

Moles of H₂ = 18 g H₂ × (1 mol H₂/2.016 g H₂) = 8.93 mol H₂

Moles of H₂O = 8.93 mol H₂O × (2 mol H₂O/2 mol H₂) = 8.93 mol H₂O

Theoretical yield of H₂O = 8.93 mol H₂O × (18.02 g H₂O/1 mol H₂) = 160 g H₂O

A .115 L sample of dry air has a pressure of 1.0895633 atm at 377 K. What is the volume of the sample if the temperature is incr

matrenka [14]

Answer:

V= 0.147 L

Explanation:

This is simply the application of combined gas law twice, to find the unknowns.

Combined gas law states that: $PV = nRT$

P= pressure of air

V= volume of air

n= moles of air

R= Universal gas constant ( 0.08205 L atm mol⁻¹ K⁻¹)

T= Absolute temperature in kelvin.

$n=\frac{P * 0.115}{R * 377}$

Now, applying the same gas law at 483K and substituting for n

$V = \frac{P * 0.115}{R * 377} * \frac{R* 483}{P}$

V= $\frac{0.115 * 483}{377}$

V= 0.147 L
