Answer:
Mass = 75.6 g
Explanation:
Given data:
Temperature of gas = 17°C
Volume of gas = 575 mL
Pressure of gas = 85000 mmHg
Mass of gas = ?
Solution:
Temperature of gas = 17°C (17+273 =290 K)
Volume of gas = 575 mL (575/1000 = 0.575 L)
Pressure of gas = 85000 mmHg (85000/760 = 111.8 atm)
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
111.8 atm × 0.575 L = n×0.0821 atm.L/ mol.K × 290 K
64.285 atm. L = n×23.809 atm.L/ mol
n = 64.285 atm. L / 23.809 atm.L/ mol
n = 2.7 mol
Mass of nitrogen gas:
Mass = number of moles × molar mass
Mass = 2.7 mol × 28 g/mol
Mass = 75.6 g
Answer:
are you showing us how or asking us because you put " how to" which means your showing us if your asking then you should put " How do you"
Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
