Answer:
0.1795 M
Explanation:
From the given information:
The equation is:
From the above equation, the reaction will go to completion due to the strong base:
At the equivalence point, moles of acid (HF) will be equal to moles of base (KOH)
Thus. since moles of HF = moles of KOH
Then; 0.020 × 0.393 M = 0.02379 × (x) M
(x) M = 
(x) = 0.3304 M
Thus, the molarity of KOH = 0.3304 M
Using the balanced neutralization reaction;
moles of HF = moles of KOH = moles of conjugate base = 0.00786 mol
∴
Volume = 0.020 L + 0.02379 L
Volume = 0.04379 L
Volume of the solution = 0.04379 L
Therefore; Molarity = 
Molarity = 
Molarity = 0.17949 mol/L
= 0.1795 M
The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.
<h3>What is a pond?</h3>
Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.
A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.
This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.
Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

Answer:
1.125moles
Explanation:
mass of NaOH,m= 45g
molar mass of NaOH, M= 23+16+1
= 40g/mol
mole,n =m/M
n= 45/40
n=1.125mole
Answer:
34.23 g.
Explanation:
<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>
M = (no. of moles of solute)/(V of the solution (L)).
∴ M = (mass/molar mass)of C₁₂H₂₂O₁₁/(V of the solution (L)).
<em>∴ mass of C₁₂H₂₂O₁₁ = (M)(molar mass)(V of the solution (L)</em> = (1.0 M)((342.3 g/mol)/(0.10 L) = <em>34.23 g.</em>
