Answer:

  • <u><em>Saturated</em></u>

<u><em></em></u>

Explanation:

Translation:

  • <em>50 grams of solute at room temperature in a 100ml container of water, but the solute accumulated at the bottom. He heated it allowing it to dissolve just an additional 10 grams of solute. What solution did you get? Oversaturated, unsaturated, saturated or diluted</em>

<em />

<h2>Solution</h2>

A<em> saturated</em> <em>solution</em> contains the maximum amount of solute that it can dissolve at the given temperature and pressure.

If you add more solute than that it will not get <em>dissolved</em> but the extra solute will remain as a solid at the<em> bottom</em> of the <em>solution</em>.

The fact that, for the <em>solution</em> with 50 grams of solute, the <em>solute accumulated</em> at the <em>bottom</em> means that it could not dissolve more, so the solution was saturated.

By <em>heating</em> the solution it was able to <em>dissolve</em> more <em>solute </em>but the fact that yeat some <em>grams</em> were undissolved means that the solution was still saturated at the new temperature.

<em>Oversaturated</em> is an unstable state at which the solution can dissolve more solute than what the normal solubility permits. That state can be reached only under special procedures which would require a different description.

Thus, you get a <em>saturated solution</em>.

How many formula units make up 12.8 g of magnesium chloride (MgCl2)? Express the number of formula units numerically.
Cloud [144]
<h3>Answer:</h3>

8.09 × 10²² formula units

<h3>Explanation:</h3>

Mass of MgCl₂ is 12.8 g

Required to calculate the formula units

1 mole of a compound contains the Avogadro's number formula units

That is;

1 mole = 6.022 × 10²³ formula units

<h3>Step 1: Calculate the moles of MgCl₂ in 12.8 g </h3>

The molar mass of MgCl₂ is 95.211 g/mol

Number of moles = Mass ÷ molar mass

Moles of MgCl₂ = 12.8 g ÷ 95.211 g/mol

                          = 0.1344 mole

<h3>Step 2: Calculate the formula units of MgCl₂</h3>

1 mole =  6.022 × 10²³ formula units

Therefore;

Number of formula units = Moles × 6.022 × 10²³ formula units

                                    = 0.1344 mole × 6.022 × 10²³ formula units

                                     = 8.09 × 10²² formula units

Therefore, there are 8.09 × 10²² formula units in 12.8 g of MgCl₂

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
Mekhanik [1.2K]

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
