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

The answer for the following answer is mentioned below.

Explanation:

To find the mass of calcium nitrate ( ) is :

No of calcium are 1

No of nitrogen are 2

No of  oxygen are 6

=

So therefore;

No of nitrogen are 2

No of  oxygen are 6

Mass of  ( ) :

molecular mass of calcium =40

molecular mass of nitrogen = 14

molecular mass of oxygen = 16

 = (14×2) + (16×6)

           = 28 + 96

           = 124

 = 40 + 124

 = 164 grams

Therefore the mass of calcium nitrate ( ) is 164 grams

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023
