What is the scaling factor if the molar mass of this compound, having an empirical formula of ch2o, is 150 g/mol

The scaling factor is 5

Considering the question given above, the following data were obtained:

Empirical formula = CH₂O

Molar mass of compound = 150 g/mol

The scaling factor can be obtained as follow:

[CH₂O]n = 150

[12 + (2×1) + 16]n = 150

[12 + 2 + 16]n = 150

30n = 150

Therefore, the scaling factor is 5

The answer to your question is Scaling factor = 5

Explanation:

Data

Empirical formula CH₂O

molar mass = 150 g/mol

Empirical formula is a chemical formula that shows the simplest proportions of the elements of that formula.

Process

1.- Calculate the molar mass of the Empirical formula

    CH₂O = (12 x 1) + (2 x 1) + (16 x 1)

               = 12 + 2 + 16

               = 30 g

2.- Divide the molar mass of the molecular formula by the molar mass of the empirical formula.

                   150g / 30g = 5      Scaling factor = 5

3.- Molecular formula

                    5(CH₂O) = C₅H₁₀O₅

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.
