A sample of fluorine gas is confined in a 5.0-L container at 0.432 atm and 37 °C. How many moles of gas are in this sample?
Ahat [919]

Answer:

About 0.08486 moles

Explanation:

PV=nRT, when P is the pressure in atmospheres, V is the volume in liters, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin.

0.432 \cdot 5= n \cdot 0.0821 \cdot 310

n\approx 0.08486 moles

Hope this helps!

the reaction of 50 mL of gas with 50 mL of gas via the equation: Cl2(g) + C2H4(g) ➔ C2H4Cl2 (g) will produce a total of ________
spin [16.1K]

Explanation:

The given data is as follows.

      50 ml of Cl_{2},       50 ml of C_{2}H_{4}

And, it is known that at STP 1 mole of a gas occupies 22.4 L. Hence, moles present in 50 ml of gas are as follows.

          \frac{50}{22.4 \times 1000}      (As 1 L = 1000 ml)

          = 2.23 \times 10^{-3} moles

So, according to the given equation 2.23 \times 10^{-3} moles of Cl_{2} reacts with 2.23 \times 10^{-3} moles of C_{2}H_{4}.

Hence, moles of C_{2}H_{4}Cl_{2} is equal to the moles of C_{2}H_{4} and Cl_{2}.

Therefore, moles of C_{2}H_{4}Cl_{2} = 2.23 \times 10^{-3} moles

           1 mole of C_{2}H_{4}Cl_{2} = 22.4 L

   2.23 \times 10^{-3} moles = 22.4 \times 2.23 \times 10^{-3} moles        

                                = 50 ml of product

Thus, we can conclude that 50 ml of products if pressure and temperature are kept constant.

Carbon Monoxide is a toxic gas that is colorless and tasteless. How many moles of CO are in 1 L of the gas at STP?
Debora [2.8K]

Answer:

0.045 moles

Explanation:

Given data:

Moles of CO = ?

Volume of gas = 1 L

Temperature and pressure = standard

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

n = PV/RT

n = 1 atm× 1L / 0.0821 atm.L/mol.K × 273 K

n = 1 atm.L / 22.41 atm.L/mol

n = 0.045 mol
