Experimental errors occurs in the execution of experiment design. Example of experimental errors are  mistakes in data entry, systematic error, and random error caused by environmental conditions. Did you even heard about type I and type II error? Because that may be the 2 ways you are looking for.  
A false positive is called a Type I error, and it is the type of error that incorrectly rejecting the null hypothesis in the favor of the alternatives.
A false negative is what you called Type II error, it is the opposite of type I error and it is the false acceptance of the null hypothesis. A type II errors are not seen to be as problematic as type I error, type I error is more serious than type II error, because you have wrongly rejected the null hypothesis.

if you are told to get 100 mL of stock solution to use to prepare smaller size sample for an experiment, which piece of glasswar
fgiga [73]

Answer:

A beaker  

Step-by-step explanation:

Specifically, I would use a 250 mL graduated beaker.

A beaker is appropriate to measure 100 mL of stock solution, because it's easy to pour into itscwide mouth from a large stock bottle.

You don't need precisely 100 mL solution.

If the beaker is graduated, you can easily measure 100 mL of the stock solution.

Even if it isn't graduated, 100 mL is just under half the volume of the beaker, and that should be good enough for your purposes (you will be using more precise measuring tools during the experiment).

How many moles of aluminum are equivalent to 4.816x10^24 atoms? 12.5 8 1.25 0.8
kotegsom [21]

Answer:

8

Explanation:

1 mole = 6.02 × 10²³ atoms

? moles = 4.816 × 10²⁴ atoms.

? Moles = 4.816 × 10²⁴ ÷ 6.02 × 10²³

? Moles = 8 moles

8 moles of aluminum = 4.816 × 10²⁴
