a solution is two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (ex: sugar). The solvent is the one doing the dissolving (ex: water).
i learned this in science last year i hope this helped :)
Answer: The number of moles of the weak acid in the solution is 0.00396
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a)
The balanced chemical reaction is:
1 mole of base uses = 1 mole of
0.00396 moles of base use =
moles of
Thus the number of moles of the weak acid in the solution is 0.00396
The answer is 15.5 gallons.
The mass of water in the tank, given the data from the question is 549594 g
<h3> Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mass of water in the tank</h3>
From the question given above, the following data were obtained:
- Mole of water = 30533 moles
- Molar mass of water = 18 g/mol
- Mass of water = ?
The mass of the water can be obtained as follow:
Mass = mole × molar mass
Mass of water = 30533 × 18
Mass of water = 549594 g
