<u>Answer:</u> The minimum volume of the container must be 460.54 L.
<u>Explanation:</u>
Density is defined as the ratio of mass and volume of a substance.
......(1)
Given values:
Volume of water = 0.37 L = 370 mL (Conversion factor: 1 L = 1000 mL)
Density of water = 1.00 g/mL
Putting values in equation 1, we get:
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
The equation used is:
......(2)
Given mass of water = 370 g
Molar mass of water = 18 g/mol
Putting values in equation 2, we get:
At STP conditions:
1 mole of a gas occupies 22.4 L of volume
Applying unitary method:
20.56 moles of water will occupy = 
of volume.
Hence, the minimum volume of the container must be 460.54 L.
The balanced equation of NaOH and H2SO4 would be:
2NaOH + H2SO4 = Na2SO4 + 2H2O
To determine the concentration of NaOH, we first find the moles of NaOH used in the reaction. We start with the the concentration and volume of H2SO4. We do as follows:
2.00 M H2SO4 ( 0.25 L ) = 0.5 mol H2SO4
0.5 mol H2SO4 ( 2 mol NaOH / 1 mol H2SO4) = 1 mol NaOH
Molarity = 1 mol NaOH / 2.00 L NaOH solution = 0.5 M NaOH solution
One correct thging is that there are the same amount of positive and negative atoms
Answer:
2.0 M
Explanation:
Step 1: Given data
- Mass of NaCl (solute): 2.93 g
- Volume of the solution: 0.025 L
Step 2: Calculate the moles corresponding to 2.93 g of NaCl
The molar mass of NaCl is 58.44 g/mol.
2.93 g × 1 mol/58.44 g = 0.0501 mol
Step 3: Calculate the molarity of the solution
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0501 mol/0.025 L = 2.0 M
The best answer would be answer B. "the atom has a cloud of positive charge....."
