Answer: The new concentration of the solution is 0.143 M.
Explanation:
Given:
= 300.0 mL,
= 0.335 M
= 700.0 mL,
= ?
Formula used is as follows.

Substitute values into the above formula as follows.

Thus, we can conclude that the new concentration of the solution is 0.143 M.
Answer:
[HCl] = 4.54 M
Explanation:
14.2 % by mass is 14.2 g in 100 g of solution.
Let's calculate the moles of our solute, HCl
14.2 g / 36.45 g/mol = 0.389 mol
Molarity is mol/L (moles of solute in 1L of solution)
Let's determine the volume of solution with density
Solution density = Solution mass / Solution volume
Solution volume = Solution mass / Solution density
Solution volume = 100 g / 1.1684 g/mL → 85.6 mL
For molarity, we need the volume in L. Let's make the unit change.
85.6 mL . 1 L/1000mL = 0.0856L
Molarity is 0.389 mol / 0.0856L → 4.54 M
I think it’s A for the first one and C for the second one
Answer: it should be in your reference table
I don’t have an earth science table with me but it is a whole page of wind belts
