Question

calculate the percentage composition of sodium acetate

Answer 1

Answer:

chemical formula shows the elemental composition of a substance: the ... NaCl: one sodium atom, one chlorine atom in a formula unit .... find percent composition.

Answer 2

Answer:

Na=23, C=12, O=16, H=1

Molecular Formula : CH3COONa

Molecular Mass :

CH3COONa

= 12+1.3+12+16+16+23

=12+3+12+16+16+23

After addition

= 82 amu

Mass % of different elements -

1. Na -->

= 23/82 x 100

= 28.05 %

2. C -->

= 24/82 x 100

= 29.27%

3. H -->

= 3/82 x 100

= 3.66%

4. O -->

=32/82 x100

= 39.02%
