Answer:
0.0102 L or 10.2 mL
Explanation:
From the question given above, the following data were obtained:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole / Volume
With the above formula, we can obtain the volume as follow:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity = mole / Volume
0.250 = 0.00255 / volume
Cross multiply
0.250 × volume = 0.00255
Divide both side by 0.250
Volume = 0.00255 / 0.250
Volume = 0.0102 L
Covert 0.0102 L to mL.
1 L = 1000 mL
Therefore,
0.0102 L = 0.0102 L × 1000 / 1 L
0.0102 L = 10.2 mL
Thus, the volume is 0.0102 L or 10.2 mL

Answer: Option (c) is the correct answer.
Explanation:
Cohesion is the property of particles of sticking together.
It is known that water is a polar solvent and due to this there is partial positive charge on hydrogen ion and partial negative charge on oxygen atom. This polarity of water causes cohesion which further helps in the upward movement of water molecules up through the plant.
Work is defined in physics as a force causing the movement—or displacement—of an object. Using physics, you can calculate the amount work performed.
