The polarity of a water molecule comes from the uneven distribution of electron density of hydrogen and oxygen atom. The oxygen in the water molecule is more electronegative than the hydrogen. Water has a partial positive charge near the hydrogen atom and a partial negative charge near the oxygen atom. The result of this electrostatic attraction results in the bond called hydrogen bond. Also, because of this bond, it has the ability to dissolve most of the solutes due to its polarity and bonding.

to solve the amount of sulfuric acid to maximize the profitwe need to establish the profit
let S(x) = 100x the selling price
P = S(x) – C(x)
P = 100x – ( 100,000 + 50x + 0.0025x^2)
P = 50x – 100000 – 0.0025x^2
Getting the first derivative and equating it to 0
0 = 50 – 0.005x
X = 10000 units of sulfuric acid
But the capacity is only 7000 units
So 7000 units should be manufactured

The moles of potassium nitrate present in the 50 ml of 0.2M solution has been 4 moles.
Molarity can be defined as the moles of solute in a litre of solution. The solution of potassium nitrate has been prepared to be of Molarity 0.2 M. The moles of solute present in the solution can be calculated as:
Molarity = moles volume (L)
The given volume = 50 ml
1000 ml = 1 L
50 ml = 0.05 L
Molarity of the solution = 0.2 M
The moles of solute:
0.2 = moles 0.05
Moles of Potassium nitrate = 4
The moles of potassium nitrate present in the 50 ml of 0.2M solution has been 4 moles.
For more information about the moles of solute, refer to the link:
n = M x V
n = 0.20 x 0.05
n = 0.01 moles of solute

Answer:
The concentration of CaCl2 in this solution is 0.564 molar (option A)
Explanation:
Step 1: Data given
Mass of CaCl2 = 23.7 grams
Mass of water = 375 grams
Density of solution is 1.05 g/mL
Step 2: Calculate total mass
Total mass = mass of CaCl2 + mass of water
Total mass = 23.7 grams + 375 grams = 398.7 grams
Step 3: Calculate volume of the solution
Density = mass / volume
Volume = mass / density
Volume = 398.7 grams / 1.05 g/mL
Volume = 379.7 mL = 0.3797 L
Step 4: Calculate moles CaCl2
Moles CaCl2 = mass CaCl2 / molar mass CaCl2
Moles CaCl2 = 23.7 grams / 110.98 g/mol
Moles CaCl2 = 0.214 moles
Step 5: Calculate concentration
Concentration of CaCl2 = moles / volume
Concentration of CaCl2 = 0.214 moles / 0.3797 L
Concentration of CaCl2 = 0.564 mol / L = 0.564 molar
The concentration of CaCl2 in this solution is 0.564 molar (option A)
