It means that each section of the test that you took you scored 1130 through 1210.
Answer:
Between 1790 and 1820 they tended to be like houses where all prisoners not in solitary confinement lived in common rooms and ate in large dining halls. It was difficult to avoid putting more and more offenders in the large rooms, and this caused overcrowding and management problem
Explanation:
Physical Weathering
This especially happens with granitic rocks as they were cooling, like at Yosemite National Park. Freeze-thaw: When water freezes, it expands. If moisture seeps into cracks before winter, it can then freeze, driving the rocks apart.
Taking into account the definition of Avogadro's Number, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
<h3>
Avogadro's Number</h3>
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
<h3>This case</h3>
Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 7.80×10²² molecules are contained in how many moles of HCl?
amount of moles of HCl= (7.80×10²² molecules × 1 mole)÷ 6.023×10²³ molecules
<u><em>amount of moles of HCl= 0.1295 moles</em></u>
Finally, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
