Question

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

Answer 1

The answer for the following answer is mentioned below.

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

Step-by-step 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

`Ca(NO_(3) )_(2)` = 164 grams

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