To find the mass of Ca(NO3)2 you would add up ___ Calcium, ___ Nitrogens, and ___ Oxygens.
Varvara68 [4.7K]

The answer for the following answer is mentioned below.

  • Therefore the mass of calcium nitrate ( Ca(NO_{3} )_{2}

Explanation:

To find the mass of calcium nitrate (Ca(NO_{3} )_{2} ) is :

No of calcium are 1

No of nitrogen are 2

No of  oxygen are 6

( NO_{3} ){2} = N_{2} O_{6}

So therefore;

No of nitrogen are 2

No of  oxygen are 6

Mass of  (Ca(NO_{3} )_{2} ) :

molecular mass of calcium =40

molecular mass of nitrogen = 14

molecular mass of oxygen = 16

N_{2} O_{6}  = (14×2) + (16×6)

           = 28 + 96

           = 124

Ca(NO_{3} )_{2}  = 40 + 124

<u><em></em></u>Ca(NO_{3} )_{2}<u><em>  = 164 grams</em></u>

Therefore the mass of calcium nitrate ( Ca(NO_{3} )_{2} ) is 164 grams

When two monosaccharides condense to form a disaccharide, what is the other product of the reaction? enter the molecular formula
koban [17]

When two monosaccharides combine to make a disaccharide, water is the byproduct.

<h3>What are monosaccharides ?</h3>

The most fundamental building blocks from which all carbohydrates are constructed are monosaccharides, commonly known as simple sugars. They are the most basic types of sugar. They are typically crystalline solids, colorless, and soluble in water.

These three monosaccharides—glucose, fructose, and galactose—are crucial for nutrition. Six carbon atoms, twelve hydrogen atoms, and six oxygen atoms make up each single sugar molecule.
