Part 1) There is a storage container with 5.25 tons of Ammonia (NH3). How many molecules of Ammonia are there?

1.69×10²⁹ molecules.

Explanation:

The following data were obtained from the question:

Mass of Ammonia (NH3) = 5.25 tons

Molecules of Ammonia (NH3) =.?

Next, we shall convert 5.25 tons to grams (g). This can be obtained as follow:

1 ton = 907184.74 g

Therefore,

5.25 ton = 5.25 ton × 907184.74 g / 1 ton

5.25 ton = 4762719.885 g

Therefore, 5.25 tons is equivalent to 4762719.885 g

Finally, we shall determine the number of molecules of ammonia, NH3 in 4762719.885 g. This can be obtained as follow:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of ammonia, NH3 also contains 6.02×10²³ molecules.

1 mole of ammonia, NH3 = 14 + (3x1) = 14 + 3 = 17 g

17 g of ammonia, NH3 contains 6.02×10²³ molecules.

Therefore, 4762719.885 g of ammonia, NH3 will contain = (4762719.885 × 6.02×10²³) / 17 = 1.69×10²⁹ molecules.

From the calculations made above,

5.25 tons (4762719.885 g) of ammonia, NH3 contains 1.69×10²⁹ molecules.

Bill Nye – he’s not a pushy guy, he just wants you to learn about pressure.

THE BIG IDEAS

Pressure is a pushing force spread out over an area.

Pressure acts in all directions at once.

Liquids and gases exert pressure.

Astronauts wear pressurized space suits to keep air in their blood from making fizzy bubbles?

Your blood pressure is a measure of how hard your blood presses against the walls of your arteries?

Hovercrafts are vehicles that float above water by air pressure?
