Answer:

V = 11.2 L

Explanation:

Hello there!

In this case, according to the ideal gas equation:

PV=nRT

It is possible to compute the volume as shown below:

V=\frac{nRT}{P}

Whereas the moles are computed are computed given the mass and molar mass of oxygen:

n=16g*\frac{1mol}{32g} =0.5mol

Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:

V=\frac{0.5mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=11.2L

Best regards!

How many liters of fluorine gas, at standard temperature and pressure, will react with 23.5 grams of potassium metal? Show all o
Sladkaya [172]

Potassium 23.5g/39.0983g/mol = 0.601mol

The Ratio of reactants is 2 to 1 so (0.601mol)/2 = 0.3005mol

Therefore 0.3005mol of F2 is needed to find liters use

formula V = nRT/P (V)Volume = 22.41L

(T)Temperature = 273K or 0.0 Celsius

(P)Pressure = 1.0atm

<span>(R)value is always .08206 with atm n = 0.3005moles (273)(.08206)(0.3005)/1 = V V = 6.7319 Liters</span>
