6 0

Answer:

1 mole of any material contains 6.023×1023 elementary particles. Hence, by ratio and proportion, 5.61mol of diatomic hydrogen gas contains 5.61×6.023×1023 hydrogen molecules =3.3789×1024 H2 molecules.

Hey there! Here are 10 fun facts to brighten your day!

1. Three presidents, all Founding Fathers—John Adams, Thomas Jefferson, and James Monroe—died on July 4. Presidents Adams and Jefferson also died the same year, 1826; President Monroe died in 1831. Coincidence? You decide.

2. The Barbie doll’s full name is Barbara Millicent Roberts, from Willows, Wisconsin. Her birthday is March 9, 1959, when she was first displayed at the New York Toy Fair.

3. There actually aren’t “57 varieties” of Heinz ketchup, and never were. Company founder H.J. Heinz thought his product should have a number, and he liked 57. Hint: Hit the glass bottle on the “57,” not the bottom, to get the ketchup to flow.

4. One of President John Tyler’s grandsons is still alive today—and he was born in 1790. How is this possible? President Tyler, the 10th US president, was 63 when his son Lyon Tyler was born in 1853; Lyon’s son was born when he was 75. President Tyler’s living grandson, Harrison Tyler is 92. Lyon’s other son Lyon Jr. passed away in 2020 at the age of 95. The Tyler family still maintains the President’s home, Sherwood Forest Plantation in Virginia.

5. The tallest man ever recorded was American giant Robert Wadlow (1918–1940), who stood 8 feet 11 inches. Wadlow’s size was the result of an abnormally enlarged pituitary gland.

6. The oldest person ever to have lived (whose age could be authenticated), a French woman named Jeanne Louise Calment, was 122 years old when she died in 1997.

7. Sliced bread was first manufactured by machine and sold in the 1920s by the Chillicothe Baking Company in Missouri. It was the greatest thing since…unsliced bread?

8. The Earl of Sandwich, John Montagu, who lived in the 1700s, reportedly invented the sandwich so he wouldn’t have to leave his gambling table to eat.

9. The first college football game was played on November 6, 1869, between Rutgers and Princeton (then known as the College of New Jersey) in New Brunswick, New Jersey. Rutgers won.

10. Experiments in universities have actually been carried out to figure out how many licks it takes to get to the center of a Tootsie Pop, both with the machine and human lickers (because this is important scientific knowledge!). The results ranged from 252 to 411.

Large objects that form dense gravity wells in place<br> PLZ HELP ME !
kari74 [83]
A gravity well is the pull of gravity that a large body in space exerts. The larger the body (the more mass) the more of a gravity well it has. The Sun has a large (or deep) gravity well. Asteroids and small moons have much shallower gravity wells. Anything on a planet or moon is considered to be at the bottom of the gravity well. Entering space from the surface of a planet or moon means climbing out of the gravity well, something that often takes a huge amount of energy. The larger a planet or moon's gravity well is, the more energy it takes to achieve escape velocity and blast a ship off of it.
