The first step to answer this question is to convert the volume of solution needed, that is in liters, to mililiters.

$0.1L\cdot\frac{1000mL}{L}=100mL$

Use the concentration of the solution to find how many mg are present in 100mL of the solution:

$100mL\cdot\frac{10mg}{mL}=1000mg$

Now, convert the amount of mg present in the solution to grams:

$1000mg\cdot\frac{1g}{1000mg}=1g$

It means that 1g of NaOH is needed to prepare 0.1L of a 10mg/mL solution.

What best describes why hair gel is considered a noncrystalline solid?

ad-work [718]

Given what we know, we can confirm that hair gel is considered a noncrystalline solid due to Atoms in the hair gel having no particular order or pattern.

<h3>What is a noncrystalline solid?</h3>

This is a solid whose atoms are amorphous.
What this means is that the atoms lack a specific order like most solids.
The most common example of this is glass.

Therefore, given the definition of a noncrystalline solid as a solid whose atoms lack a specified order, we can confirm that the second option which states that "Atoms in the hair gel having no particular order or pattern" is correct.
