Answer 1

Answer:Na2S2O3

Explanation:

Na: 29.11 g

S: 40.51 g

O: 30.38 g

First step is to convert from mass to mols:

Na: 29.11\ 22.990= 1.266 moles  (4 significant figures)

S: 40.51\ 32.006 = 1.263 moles

O: 30.38\ 16 = 1.899 moles

Second step is to put the moles as ratios

1.266: 1.263: 1.899

Third step is to divide each number of moles by the least amount of moles between them which is 1.266 (keep in mind which mole is for which element)

1.266\1.263 : 1.263\1.263: 1.899\1.263

Forth step:

1:1:1.5 ( ratios and numbers should be in whole numbers when we need to identify the empirical formula; therefore, we need to multiply the whole ratio by 2 to get rid of the decimals)

Fifth Step:

(1:1:1.5 ) *2 = 2:2:3

Sixth step: the empirical formula

Na2S2O3
