Suppose you are a food chemist working for a company that makes and manufactures soda. Your job is to create a new soft drink wi

th the ingredients available to you. There is one problem—you need 1 liter of phosphoric acid solution, and the phosphoric acid available to use has a concentration of 0.01 M. This is much too high to add to your soda without distorting the flavor. Typically, there are about 45 milligrams of phosphoric acid per 12 ounce can of soda. Here is your task:
Convert the 45 milligrams of phosphoric acid (H3PO4) into grams and then into moles.
0.00046 moles or 4.6×10-4 moles
Given that 12 ounces is equal to about 0.35 liter, find the molarity of the phosphoric acid in a typical can of soda (45 milligrams). 0.0013 M or 1.3×10-3 M
Using the dilution equation, determine how much of the stock solution (0.01 M H3PO4) you will need to make 1 liter of the concentration typically used in soda.
0.13 liter or 130 milliliters

Answer:

The answer to your question is given after the questions so I just explain how to get it.

Explanation:

a)

Get the molecular weight of Phosphoric acid

        H₃PO₄ =  (3 x 1) + (31 x 1) + (16 x 4)

                    = 3 + 31 + 64

                    = 98 g

         98 g -----------------  1 mol

      0.045 g ---------------   x

          x = (0.045 x 1) / 98

          x = 0.045 / 98

          x = 0.00046 moles or 4.6 x 10 ⁻⁴

b)

Molarity = \frac{moles}{volume}

Molarity = \frac{0.00046}{0.35}

Molarity = 0.0013 or 1.31 x 10⁻³

c)

Formula            C₁V₁ = C₂V₂

                              V₁ = C₂V₂ / C₁

Substitution

                              V₁ = (0.0013)(1) / 0.01

Simplification and result

                              V₁ = 0.0013 / 0.1

                              V₁ = 0.13 l = 130 ml

♔♔Can water stay liquid below zero degrees Celsius?✞♡♡♡​
astra-53 [7]

Answer:

Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure. When we apply pressure to a liquid, we force the molecules to get closer together.

Explanation:

Hope this helps you. Have a nice day.^_^

Please mark as brainliest. It helps a lot:)

What is an air mass? Where on Earth might you find a hot and dry air mass?
igor_vitrenko [27]
An air mass is a large volume of air in the atmosphere thats mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere/10 miles into the atmosphere. an air mass over northern Canada is a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

zysi [14]

Answer : The complete question is attached in the answer.


Explanation : In the given question an alkene is treated with alkylhalide in presence of methylene dichloride it gives a corresponding alkylbromide species.


The mechanism follows markonikov's addition rule, and the major product thus formed is bromine which is attached to least substituted carbon atom ad minor is bromine attached to highly substituted carbon atom.
