The Gateway Arch in St. Louis, MO is approximately 630 ft tall. How many U.S. half dollars would be in a stack of the same heigh
zhannawk [14.2K]

Answer:

To equal the height of the Gateway Arch in St. Louis, it would take <u>76810 half dollars. </u>

Explanation:

If the Gateway Arch in St. Louis is 630 feet high, how many half dollars will it take to equal the height if each half dollar is 2.15mm thick?

First, we convert the ft to cm and the cm to mm.

- 1 ft = 30.48 cm

630 ft = 19202.4 cm

- 19202.4 cm = 192024 mm

Now, if a half dollar is 2.15 mm thick, how many half dollars would it take to equal the height of 192024 mm?

1 half dollar = 2.15 mm

X                 = 192024 mm

X = 192024 mm / 2.15 mm

X = 76810 half dollars.

The polar isopropanol molecules are attracted to
Sergio [31]

When water (H2O) is added to liquid isopropanol to form a solution, then polar isopropanol molecules are attracted to polar water molecules at the surface of the water. It forms a solution of rubbing alcohol.

<h3>Isopropanol and water in the solution</h3>

Isopropyl alcohol is water-soluble and forms hydrogen bonds with molecules of water (H2O).

When H2O is added to liquid isopropanol to form a solution, H2O spread in a uniform way in the solution.

These isopropanol molecules can surround H2O molecules, which are carried into the solution.
