Answer:
636 mm Hg
Explanation:
The pressure in the gas container is equal to the atmospheric pressure minus the height of mercury:
Atmospheric pressure = 722 torr = 722 mm Hg
Height = 8.60 cm = 86 mm Hg
Pressure = 722 - 86 = 636 mm Hg
So none of the given options is correct, the correct answer is 636 mm Hg.
Answer:
so with every stoichiometry problem with a mass it will make it so you can do the conversion factor with reactants or products.
if you dont understand unit conversions try to study how to set it up. anyways
a.) C12H22O11 has a mass of 342.01 Grams per mole
divide 1.202 G by 342.01 G to get 0.004 miles
b.) you're just taking the AMU of each element in the chemical multiply it by how many there is of it in the chemical, then divide it by the mass of a mole of the chemical.
c.) you take your answers of part b and multiply them by Avogadro's number
Answer:
