See below.

Step-by-step explanation:

The author is probably reminding us that knowing the origins of words helps us to remember what they mean.

If "verde" means "green", the "verd" in "verdigris" probably means that verdigris is green.

However, the "verd" in verdigris domes from other languages.

It was originally Latin "viride aeris" (green brass).

In old French it became "verte de Grèce" (green of Greece). The modern French spelling is "vert-de-gris" (green of grey).

The English word "verdigris" comes from the French words.

How many liters of 0.37 M solution can be made with 29.53 grams of lithium fluoride.<br> (LiF)?
dsp73

Answer:

V = 3.1 L      

Explanation:

Given data:

Molarity of solution = 0.37 M

Mass of LiF = 29.53 g

Volume of solution = ?

Solution:

Number of moles of LiF:

Number of moles = mass/molar mass

Number of moles = 29.53 g/ 25.94g/mol

Number of moles = 1.14 mol

Volume:

Molarity = number of moles of solute / Volume in L

0.37 M = 1.14 mol / V

V = 1.14 mol / 0.37 M

V = 3.1 L         (M = mol/L)
