Liquids and solids are left out of the equilibrium constant expression because their concentrations remain constant during react

ions. What is the molarity concentration of liquid water at 25.0 LaTeX: ^\circ ∘C given that its density is 0.997 g/mL at that temperature?
a.23.5 M
b.0.997 M
c.0.180 M
d.0.156 M
e.55.3 M

Answer:

55.3 M

Explanation:

Given temperature = 25°C

Density = 0.997 g/mL

Based on density the mass of water per L = 997 grams

The molar mass of water = 18

The moles of water = \frac{mass}{molarmass}=\frac{997}{18}=55.3

The molarity is defined as the moles of water per litre.

The moles = 55.3

Volume = 1 L

So molarity = 55.3 /1 = 55.3 M

1. A container holds four times as many moles of CO2 as O2. If the total pressure in the container is 20. atm,
Hitman42 [59]

Answer:

Partial pressure of CO2 = 16 atm

Explanation:

Total number of moles of gases = 4+1 = 5 moles

Mole fraction of CO2 = 4/5

Partial pressure of CO2 = mole fraction of CO2 × total pressure

Partial pressure of CO2 = (4/5) × 20

Partial pressure of CO2 = 16 atm

How much energy is released when 22.4g of CH4 is burned?
solniwko [45]

The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
