Solid water is less dense than liquid water.
Answer:
1. mol/L
2. 0.120 M
Explanation:
1. Molarity is equal to the moles of solute divided by the liters of solution. The units of molarity are mol/L.
2.
Step 1: Given data
- Mass of sodium chloride (solute): 5.25 g
- Volume of solution (V): 750.0 mL = 0.7500 L
Step 2: Calculate the moles of solute (n)
The molar mass of NaCl is 58.44 g/mol.
n = 5.25 g × 1 mol/58.44 g = 0.0898 mol
Step 3: Determine the molarity of the solution
We will use the definition of molarity
M = n/V
M = 0.0898 mol / 0.7500 L = 0.120 M
4. density, temperature, surface tension.
7. extensive properties- uses mass and volume depends on tbe amount of substance present.
