548.55 grams of aluminum hydroxide should theoretically form.
Explanation:
Balanced equation for the reaction:
3 NaOH + Al ⇒ Al(OH)3 +3 Na
DATA GIVEN:
mass of NaOH = 842 grams, atomic mass =39.9 grams/mole
mass of Al = 750 grams, atomic mass = 26.9 grams/mole
aluminum hydroxide theoretical yield = ?
Moles of NaOH reacted
number of moles =
putting the values in the equation
NaOH =
= 21.1 MOLES OF NaOH
Al =
= 27.8 moles
from the equation
from 3 moles of NaOH 1 mole of Al(OH)3 is produced
21.1 moles of NaOH will react to give x moles of Al(OH)3
=
7.03 moles of Al(OH)3 is formed.
and
1 mole of Al(OH)3 is formed from 1 mole of Al in the reaction
so, 27.8 Moles will react to give give 27.8 moles of Al(OH)3 limiting reagent of the given reaction is NaOH
mass of Al(OH)3 =7.03 x 78 (atomic mass of Al(OH)3)
= 548.55 grams
theoretical yield from the given data is 548.55 grams
Answer:
Final pressure in (atm) (P1) = 6.642 atm
Explanation:
Given:
Initial volume of gas (V) = 12.5 L
Pressure (P) = 784 torr
Temperature (T) = 295 K
Final volume (V1) = 2.04 L
Final temperature (T1) = 310 K
Find:
Final pressure in (atm) (P1) = ?
Computation:
According to combine gas law method:
⇒ Final pressure (P1) = 5,048.18877 torr
⇒ Final pressure in (atm) (P1) = 5,048.18877 torr / 760
⇒ Final pressure in (atm) (P1) = 6.642 atm
