As we know that there are avogadro no. of atoms in 9 g of beryllium.
1 mole of beryllium = 6.02 * 10^23 atoms
so 2.5 mole= 6.02*10^23*2.5 i.e = <span>15.055 × 10^23 atoms </span>
Answer:
the molecular weight of H2SO4 is 98.086g/mole
The precision of a tool can affect the measurement's accuracy. how specific the measurement can get (if it goes to the tenths place, hundredths, etc) can also affect the accuracy.
4300 meters = approximately 14107.61 feet.
Boiling point is 212 degrees Fahrenheit at sea level.
(Each 500 feet increase in elevation will be lowered by approximately 1 degrees Fahrenheit)
14107.61 feet divided by 500 feet = <span>28.21522
So the boiling point would be lowered by about 28 degrees Fahrenheit at 4300 meters above sea level. Which will make your new boiling point 184 degrees Fahrenheit instead of 212.
184 degrees Fahrenheit = 84.4 degrees Celcius</span>
The answer is 10. Each capital letter is an atom. The tiny numbers represent how many atoms of that type
