Answer: There are 6 different outcomes.
Explanation:
There are two options for procedure one (one or two steps) and three options for procedure two (one, two or three steps). If we multiply those options , the result is the total number of outcomes for the analysis.
2 x 3 = 6
These being
- One step on procedure one and one step on procedure two
- One step on procedure one and two steps on procedure two
- One step on procedure one and three steps on procedure two
- Two steps on procedure one and one step on procedure two
- Two steps on procedure one and two steps on procedure two
- Two steps on procedure one and two steps on procedure two
The question is typed wrong. Assuming the correct question is
How many liters of 0.98 M H2SO4 solution would react completely with 3.5 moles Ca(OH)2 ?
Answer:-
3.571 litres
Explanation:-
The balanced chemical equation for this reaction is
H2SO4 + Ca(OH)2 = CaSO4 + 2 H2O
From the balanced chemical equation we see that
1 mole of Ca(OH)2 reacts with 1 mol of H2SO4.
∴3.5 moles of Ca(OH)2 reacts with 1 x 3.5 / 1 = 3.5 mol of H2SO4.
Strength of H2SO4 = 0.98 M
Volume of H2SO4 required = Number of moles of H2SO4 / Strength of H2SO4
= 3.5 moles / 0.98 M
= 3.571 litre
4 moles
64 grams of oxygen contains 4 moles
