Answer:

0.42 mg

Explanation:

It seems the question is incomplete, however I'll use values that have been found in a web search:

"A chemist adds 55.0 mL of a 1.7x10⁻⁵ M mercury(II) iodide solution to a reaction flask. Calculate the mass in milligrams of mercury(II) iodide the chemist has added to the flask. Round your answer to 2 significant digits."

<u>Keep in mind that while the process of solving the problem remains the same, if the values in your question are different, your answer will differ as well</u>.

First we <u>calculate the moles of mercury (II) iodide</u> (HgI₂):

  • 1.7x10⁻⁵M * 55.0 mL = 9.35x10⁻⁴ mmol HgI₂

Then we<u> convert mmol to mg, using the molar mass</u> (454.4 g/mol):

  • 9.35x10⁻⁴ mmol HgI₂* 454.4 mg/mmol = 0.42 mg

Jim ran 200 meters in 30.4 seconds. Mac ran 100 meters in 30.4 seconds. Who ran faster?
VladimirAG [237]

Jim, because he ran a greater distance in the same time :)

By the way, this is a maths question

1. Be able to convert atm’s to kPa’s. (how?)
Whitepunk [10]
1.) 0.875atm x 760.0 mmHg/atm
2.)    8I
        7I                                        0
        6I                                      0
        5I                                    0
        4I                                  0
        3I                                0
        2I--------- 000000000 0I
        1I-0------------------------ I---------------        
         0             50             100           150
                      Boiling point(degrees Celsius)
3.) The warmer the molecules are the faster they move like boiling water the gases are coming out of the water
4.)no clue
5.) A {solution} is always transparent, light passes through with no scattering from solute particles which are the molecule in size. The solution is homogeneous and does not settle out. A solution cannot be filtered but can be separated using the process of distillation.

A {suspension} is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out.

<span>A {colloid} is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall effect. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible. A hydrocolloid can simply be defined as a substance that forms a gel when it comes in contact with water. Such substances include both polysaccharides and proteins.
6.)</span><span>The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Also called Brownian motion, molecular movement, pedesis.
hope that helps please mark me as brainly
