Answer:
The volume of the stock solution needed is 1L
Explanation:
Step 1:
Data obtained from the question. This include the following:
Concentration of stock solution (C1) = 6M
Volume of stock solution needed (V1) =?
Concentration of diluted solution (C2) = 1M
Volume of diluted solution (V2) = 6L
Step 2:
Determination of the volume of the stock solution needed.
With the dilution formula C1V1 = C2V2, the volume of the stock solution needed can be obtained as follow:
C1V1 = C2V2
6 x V1 = 1 x 6
Divide both side by 6
V1 = 6/6
V1 = 1L
Therefore, the volume of the stock solution needed is 1L
Answer:
the amount of air resistance depends upon the speed of the object, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.

Number of moles of sodium reacted is 2 moles. 0.04598 Kg is the mass of sodium that reacted.
Mole fraction is 1 mole ratio is 1:1
Explanation:
Balanced chemical reaction:
2 Na + 2H20 ⇒ 2NaOH + H2 (gas)
atomic mass of sodium = 22.99 g/mol
from the reaction it can be seen that 2 moles of sodium reacted to form 2 moles of sodium hydroxide soluition.
The mass of sodium reacted can be calculated from the formula:
mass = atomic mass of one mole x number of moles
mass = 22.99 x 2
= 45.98 grams is the mass of sodium, to convert it into kilograms it is divided by 1000
= 0.04598 Kg is the mass of sodium that reacted.
Mole fraction formula is:
= mole fraction ( solute Na = 2 moles, solution is NaOH =2 moles)
putting the values:
= 1 mole ratio is 1:1
Yes, it would. For a while. But then, as is human nature, we would long for socialization with other humans. But I do understand where you’re coming from.
