Calculate the number of mg of Allura Red present in an 10 fluid ounce glass of the beverage you used in this lab. Assume that th
il63 [147K]

Answer : The mass of Allura Red present in an 10 fluid ounce glass of the beverage is, 7.634 mg.

Explanation : Given,

Volume of solution = 10 fl oz = 295.735 mL

Molar mass of Allura Red = 496.42 g/mole

Concentration of Allura Red (Molarity) = 0.000052 M

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of Allura Red}\times 1000}{\text{Molar mass of Allura Red}\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

0.000052M=\frac{\text{Mass of Allura Red}\times 1000}{496.42g/mole\times 295.735mL}

\text{Mass of Allura Red}=0.007634g=7.634mg

Therefore, the mass of Allura Red present in an 10 fluid ounce glass of the beverage is, 7.634 mg.

If it takes 100 N to move a box 5 meters, what is the work done on the box?
JulijaS [17]
<h3>Answer:</h3>

500 Joules

<h3>Explanation:</h3>

<u>We are given;</u>

  • Force is 100 N
  • Distance is 5 m

We are required to calculate the work done;

  1. Work done is the product of force and distance.
  2. That is, work done = Force × distance
  3. Work is measured in Joules

Thus, in this case;

Work done = 100 N × 5 m

                  = 500 Joules

Thus, the work done in moving the box is 500 joules

Your teacher asked you to identify the stage of mitosis of a specimen under the microscope. You observed that instead of a typic
yKpoI14uk [10]

Answer:

D. Cytokinesis

Explanation:

Mitosis is the cell division that involves the synthesis of two genetically identical daughter cells. Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase. Following this four processes is another called CYTOKINESIS

Cytokinesis, which occurs after nuclear division, is the division of the cytoplasm. According to this question, the observation made when viewing the specimen was that "the cell has a narrow middle part which almost separates into two bulging ends and which looks like the number 8". This described the process of CYTOKINESIS in plant cell specifically.

Fluorine has an atomic number of 9, how many electron shells does it have?
aleksandr82 [10.1K]
2 shells because if you do the electronic configuration: 
 2,7 which adds up to 9
7 stands for the group it in and it also stands for how many electrons are in the outer shell.
the amount of spaces stands for which period its in therefore it in period 2
