1.09 Liters
The total volume of the solution formed is 1.093 L
We know that,
Ca(OH)2 = 74 g/mole
n = 55/74 = 0.743 mole
M = n/V
where,
M = mass of the solution
n = number of moles
V = Volume of solution
0.680 = 0.743 / V
V = 0.743/0.680
= 1.093 L
= 1093 ml
Therefore, the total volume of the solution formed is 1.093 L
<h3>What is molarity?</h3>
- The amount of a substance in a specific volume of solution is known as its molarity (M).
- The number of moles of a solute per liter of a solution is known as molarity.
- The molar concentration of a solution is another name for molarity.
<h3>What is the molarity unit?</h3>
- Molarity is measured in mol/L.
- The molarity, which is given as moles/liter, is the quantity of moles of solute per liter of the solution.
<h3>Example of molarity:</h3>
- The moles of solute per liter of solution is measured as molarity.
- For instance, when table salt is dissolved in water, water serves as both the solution and the solute.
- Sodium chloride weights 58.44 grams per mole.
- One molar solution, or 1M, is created by dissolving 58.44 grams of sodium chloride in one liter of water.

Answer:
20.2 °C
Explanation:
When the pressure and number of moles are constant, Charles's law may be used to solve for temperature:
T₁/V₁ = T₂/V₂ >> T₂ = T₁ (V₂/V₁)
Expressions for the volumes can be substituted and simplified:
T₂ = T₁ (V₂/V₁) = T₁ (4/3πr₂³/4/3πr₁³) = T₁ (r₂³/r₁³)
Substituting in values in the equation (where the radius r is half of the diameter) gives:
T₂ = T₁ (r₂³/r₁³) = (19.0°C) x ((51.0cm/2)³/(50.0cm/2)³) = 20.2 °C
Answer:
Mass # = Protons + Neutrons= 35
The charge is -1 because 17 protons arent equal to the 18 electrons each has a -1 charge
Explanation:
These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
