Why would other scientist want to see observations from your three trials

Chemistry
1 answer:
Vedmedyk [2.9K]2 years ago
3 0

Answer:

When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events and are reliable. Multiple trials can be done at one time. E.g. If we were testing a new fertilizer, we could test it on lots of individual plants at the same time.

Hope that helped.x

BartSMP [9]

Answer:

0.131 mol

Explanation:

To convert grams to moles, you need to use the molar mass.  The molar mass is the mass number.  You can find this on the periodic table.  The molar mass of sodium is 22.990 g/mol.

(3.02 g)/(22.990 g/mol) = 0.131 mol

What is the scaling factor if the molar mass of
Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

sf=150/30=5

Therefore, we can also infer that the molecular formula would be:

C_5H_1_0O_5

Best regards!
