The density of mercury is 13.54 g/cm3. Suppose you need 40 gm of mercury for an experiment. What volume of mercury do you need?
A)2.95 cm3
B)541.60 cm3
C)26.46 cm3
mass = volume x density
A0 2.95 cm3
The density of mercury is 13.54 g/cm3. Suppose you need 40 gm of mercury for an experiment. What volume of mercury do you need?
The correct answer is C(26.46 cm3)
To find the volume of mercury needed, we can use the formula:
Volume = mass / density
Given that the mass of mercury needed is 40 gm and the density of mercury is 13.54 g/cm³, we can substitute these values into the formula:
Volume = 40 gm / 13.54 g/cm³
Now, divide the grams (gm) by the grams per cubic centimeter (g/cm³):
Volume = 40 / 13.54 cm³
Calculating this value, we get:
Volume ≈ 2.951 cm³
Since the answer choices are in cubic centimeters (cm³) and being rounded to two decimal places, the closest option would be:
A) 2.95 cm³
Therefore, the correct volume of mercury needed for the experiment would be approximately 2.95 cm³.
