What is the volume of an object if its density is 0.362 g/ml, and its mass is 19.78 g? Express your answer to the correct number of significant figures.
a. 7.16 ml
b. 7.160
c. 54.64
d. 54.6 ml
To find the volume of an object, we can use the formula:
Volume (V) = Mass (m) / Density (d)
Plugging in the values given:
V = 19.78 g / 0.362 g/ml
Solving for V:
V ≈ 54.64088397 ml
Rounding to the correct number of significant figures, the volume is approximately 54.6 ml.
Therefore, the correct option is d. 54.6 ml.
