The answer for the following answer is mentioned below.
Explanation:
To find the mass of calcium nitrate ([tex]Ca(NO_{3} )_{2}[/tex] ) is :
No of calcium are 1
No of nitrogen are 2
No of oxygen are 6
[tex]( NO_{3} ){2}[/tex] = [tex]N_{2} O_{6}[/tex]
So therefore;
No of nitrogen are 2
No of oxygen are 6
Mass of ([tex]Ca(NO_{3} )_{2}[/tex] ) :
molecular mass of calcium =40
molecular mass of nitrogen = 14
molecular mass of oxygen = 16
[tex]N_{2} O_{6}[/tex] = (14×2) + (16×6)
= 28 + 96
= 124
[tex]Ca(NO_{3} )_{2}[/tex] = 40 + 124
[tex]Ca(NO_{3} )_{2}[/tex] = 164 grams
Therefore the mass of calcium nitrate ( [tex]Ca(NO_{3} )_{2}[/tex] ) is 164 grams
