What is the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate

Chemistry
1 answer:
Ostrovityanka [42]2 years ago
5 0

Answer: 40 + 2x14 + 6x16 = 164g/mole

54.3g x [1mole / 164g] = 0.331moles

355mL x 1L / 1000mL = 0.355L

molarity = 0.331moles / 0.355L =

00

Which option explains how some parts of a plant can be white?
just olya [345]

Some parts of a plant can be white because they do not contain chlorophyll.

Chlorophyll is a term to refer to a characteristic compound of most plants that has the function of:

  • Bring the green color to vegetables
  • Take charge of the photosynthesis process.

Some plants do not have as much chlorophyll in their systems. However, this does not affect their reproduction and growth because they have developed other feeding methods through their roots.

These plants that contain low amounts of chlorophyll have pale and white colorations because chlorophyll is what gives the plants their intense green color.

Note: This question is incomplete because options are missing. Nevertheless, I can answer it based on my prior knowledge.

How many chlorine atoms are there in 12.2 g of ccl4? How many chlorine atoms are there in 12.2 of ? 4.77×1022 atoms?
mash [69]

Answer:- 1.91*10^2^3Cl atoms.

Solution:- We have been given the grams of carbon tetrachloride and asked to calculate the number of atoms of chlorine. It is a three step conversion problem. In the first we convert the grams of carbon tetrachloride to moles of it. In second step we convert moles of carbon tetrachloride to moles of chlorine and in the third step we convert the moles of chlorine to atoms of chlorine.

For grams to mole conversion we need the molar mass of the compound. Molar mass of carbon tetrachloride is 153.82 grams per mol. If we look at the formula of carbon tetrachloride then four chlorine are present in it. It means 1 mol of carbon tetrachloride has four moles of chlorine. The calculations are as follows:

12.2gCCl_4(\frac{1molCCl_4}{153.82gCCl_4})(\frac{4molCl}{1molCCl_4})(\frac{6.02*10^2^3Clatoms}{1molCl})

= 1.91*10^2^3Cl atoms

So, there are 1.91*10^2^3Cl atoms in 12.2 grams of CCl_4 .
