Answer:
Explanation:
1 standard deviation range will look like: [average - SD, average + SD]
Here the miximum value will be: average - SD = 2.6 - 0.80 = 1.80 ml
and the maximum value will be: average + SD = 2.6 + 0.80 = 3.40ml

Answer: Compounds having the same empirical formula are:
Explanation:
Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.
In given empirical formula that is proportion of C:H:O = 1:2:1
In the proportion of C:H:O =2:4:2= 1:2:1
In the proportion of C:H:O =3:6:3= 1:2:1
In the proportion of C:H:O =1:2:2= 1:2:2
In the proportion of C:H:O =5:10:5= 1:2:1
In the proportion of C:H:O =6:12:6= 1:2:1
Compounds having the given empirical formula are:
Because chemicals they blow up
