Devising a way to achieve the goals is the most important when setting goals.
Devising a way to achieve the goals
Explanation:
The fundamental objective for progress is Breaking down any long haul objectives into littler increasingly feasible objectives that help to advance accomplishment and achievement. While defining objectives, it makes its needs unmistakable for everybody associated with the association.
The reason for objective setting is to people what they have to concentrate on the most during the up and coming quarter, which at that point encourages them to have the option to organize their assignments.
Since it accomplishes an effective, engaged and definitive way by taking the correct activities in a lesser time period throughout everyday life.
B. Composition of a substance is the same.
C. A completely new substance is formed.
D. An easily reversible process has taken place.
Answer: The molarity of solution is 1.39 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute =
= volume of solution in L
Now put all the given values in the formula of molality, we get
Therefore, the molarity of solution is 1.39 M
som temperature. More helium was added to the cylinder and the volume
as adjusted so that the gas pressure remained the same. How many
holes of helium were added to the cylinder if the volume was changed
rom 2.00 L to 2.70 L? (The temperature was held constant.) *
"our answer
!
This is a required question
B. How many grams of Helium would be added in question #2? *
Answer:
Final number of moles = 0.675 mol
Mass = 2.7 g
Explanation:
Given data:
Initial volume of gas = 2.00 L
Final volume of gas = 2.70 L
Initial number of moles = 0.500 mol
Final number of moles = ?
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = Initial number of moles
V₂ = Final volume of gas
n₂ = Final number of moles
Now we will put the values in formula.
2.00 L /0.500 mol = 2.70 L / n₂
n₂ = 2.70 L× 0.500 mol /2.00 L
n₂ = 1.35 L.mol / 2.00 L
n₂ = 0.675 mol
B)
Grams of helium added = ?
Solution:
Mass = number of moles × molar mass
Mass = 0.675 mol× 4 g/mol
Mass = 2.7 g
