(a)
Interpretation: The mass of water in grams in the cylindrical vessel needs to be calculated using the given information in question.
Concept Introduction: The volume of the cylinder is calculated as follows:
Here, r is the radius and h is the height of the cylinder.
The density is related to mass and volume as follows:
Here, m is mass and V is volume.
(a)
Explanation of Solution
The height of the cylindrical vessel is 28.0 cm and its diameter is 3.00 cm. It is filled with water at
Substitute the values,
Now, the volume of the cylinder is equal to the volume of water filled in it.
Now, density is related to mass and volume as follows:
Or,
Now, the density of water is 0.988
Substitute the values,
Therefore, the mass of water is 195.45 g.
(b)
Interpretation: The mass of water in milligrams in the cylindrical vessel needs to be calculated using the given information in question.
Concept Introduction: The volume of the cylinder is calculated as follows:
Here, r is the radius and h is the height of the cylinder.
The density is related to mass and volume as follows:
Here, m is mass and V is volume.
(b)
Explanation of Solution
The calculated mass of water can be converted into milligrams using the following conversion factor:
Thus,
Thus, the mass of water in mg is
(c)
Interpretation: The mass of water in kilogram in the cylindrical vessel needs to be calculated using the given information in question.
Concept Introduction: The volume of the cylinder is calculated as follows:
Here, r is the radius and h is the height of the cylinder.
The density is related to mass and volume as follows:
Here, m is mass and V is volume.
(c)
Explanation of Solution
The calculated mass of water can be converted into kilograms as follows:
Thus,
Thus, the mass of water in kg is
