How many moles of NH3 are there in 77.5 g of NH3?

Chemistry
1 answer:
Vanyuwa [196]2 years ago
4 0

Answer:

4.6 (Rounded)

Explanation:

Given: 77.5g of NH3

<u>77.5g of NH3</u>

         1

Plug in your units.

<u>77.5g of NH3</u>    x    <u>         mol of NH3  </u>

         1                                g of NH3

Since we are using grams, find the mass of NH3. To save you time, I'll tell you. It's 17.03052.

Now, plug is number into the equation with 1 on the top because you are trying to find 1 moles worth.

<u>77.5g of NH3</u>    x    <u>     1    mol of NH3  </u>

         1                     17.03052g of NH3

Now solve by multiplying the numbers across.

<u>    77.5x1    </u>    = <u>    77.5    </u>   = 4.55065377.

1x17.03052      17.03052

A volume of 90.0 mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H2SO4). What
Gemiola [76]

Answer:

The answer to your question:  0.7 M

Explanation:

Data

V of KOH = 90 ml

[KOH] = ?

V H2SO4 = 21.2 ml

[H2SO4] = 1.5 M

                       2KOH(aq)  +  H₂SO₄(aq)   →   K₂SO₄(aq)  +  2H₂O(l)

Molarity = moles / volume

moles of H₂SO₄ = (1.5) (21.2)

                           = 31.8

                    2 moles of KOH --------------  1 mol of H₂SO₄

                   x                           --------------  31.8 mol of H₂SO₄

                    x = (31.8)(2) / 1

                    x = 63.8 moles of KOH

Molarity = 63.8 / 90

             = 0.7 M

Explain how a drought poses a threat to life and the biosphere. Use complete sentences.
Marina CMI [18]

Answer:

A drought poses a huge threat to all life. If a drought occurred the entire food chain would disintegrate within months. There would be no water for any animals or plants. Small mammals would not be able to eat plants, and reptiles would not be able to the small animals, and so on. A drought can destroy an ecosystem in a short amount of time.

Water is only being moved into the air through water vapor, so the air will become hotter than water. Land is also not moving in the atmosphere and absorbing heat like air is, so air will also be hotter than land, depending on what the land is made of.

Through precipitation, water in the atmosphere can return to the hydrosphere or percolate into the ground to become groundwater—part of the geosphere. ... Water in the biosphere can be released into the atmosphere through transpiration in plants, or respiration in animals.
