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.

Ammonium nitrate
Ammonium = NH4+
Nitrate = NO3-
Explanation:
bases can be either strong or weak
Answer:
OH^-
Explanation:
Any substance that is able to neutralize acidity in the stomach is generally known as an antacid. There are various kinds of antacids that are in common use. It should be noted that the stomach is usually slightly acidic.
Milk of magnesia is the substance magnesium hydroxide with chemical formula Mg(OH)2. A solution of milk of magnesia contains Mg^2+ and OH^-.
Hence the negative ion contained in milk of magnesia is the hydroxide ion OH^-.
Answer:
pHe = 261 torr
pAr = 472 torr
P = 733 torr
Explanation:
The final volume for both gases is the same: V₂ = 255 mL + 475 mL = 730 mL
We can find the final partial pressure of each gas using Boyle's law.
He
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 746 torr × 255 mL / 730 mL = 261 torr
Ar
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 726 torr × 475 mL / 730 mL = 472 torr
The total pressure is the sum of the partial pressures.
P = 261 torr + 472 torr = 733 torr
