## What is the mass of moles of Ca OH 2?

The molar mass of calcium hydroxide, Ca(OH)2 , is 74.092 g/mol .

## How do you find the molar mass of caoh2?

The atomic mass of hydrogen is 1, the atomic mass of oxygen is 16, and the atomic mass of calcium is 40. We have to add this mass in the number of atoms ratio present in the molecule. So, the molecular mass of \$Ca{{(OH)}_{2}}\$ (calcium hydroxide) is 74. Therefore, the correct answer is an option (c)- 74 .

## What is the equivalent mass of Ca OH 2?

The equivalent weight of calcium hydroxide is 1/2 he mass of a mol of calcium hydroxide. 1 mol Ca(OH)2 = 74 grams Ca(OH)2 ; 1 equivalent Ca(OH)2 = 37 grams Ca(OH)2……

## What is the mass 0.015 moles of Ca Oh 2?

Calcium hydroxide has a formula mass of 74.09 g⋅mol−1 .

## What is the mass of OH?

Calcium hydroxide, Ca(OH) 2 consists of one calcium atom (A r = 40), two oxygen atoms (A r = 16) and two hydrogen atoms (A r = 1).

## What is the mass of Ca OH 2 for 10 liters?

That is a 1:1 mole ratio in which 1 mol Ca(OH)2 = 1 mol CaCO3; therefore, 100 ppm CaCO3 x (molar mass Ca(OH)2/molar mass CaCO3) = 100ppm x 74/100 = 74 mg Ca(OH)2. 74 ppm = 74 mg/L = 740 mg/10L = 0.74 g/10L.

## What is the molar mass of Al OH 3?

For example, the molecular weight of calcium hydroxide, or “slaked lime,” [Ca(OH)2] is 72.10. Because the valency of calcium in this case is 2, the equivalent weight of lime is 36.05.

## How many moles are present in 0.37 g of caoh2?

Answer : Number of moles of calcium hydroxide = 0.5 moles.

## What is the equivalent mass of chlorine?

The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 g / 2 = 8.0 g.
