the level of water in a graduated cylinder is 52.7 ml. After a solid object weighing 100 g is added, the level is 87.4 ml. What is the density of this object?
The volume = 87.4-52.7 = ?
density = mass/volume = ?
To find the density of an object, we need to use the formula:
Density = Mass / Volume
Given that the mass of the object is 100 g, we need to determine the volume of the object. We can do this by subtracting the initial volume (52.7 ml) from the final volume (87.4 ml):
Volume = Final Volume - Initial Volume
= 87.4 ml - 52.7 ml
= 34.7 ml
Now we can calculate the density:
Density = Mass / Volume
= 100 g / 34.7 ml
To find the density in a more standard unit, we can convert milliliters (ml) to grams (g):
1 ml = 1 g
Therefore,
Density = 100 g / 34.7 g
≈ 2.88 g/ml
So, the density of the solid object is approximately 2.88 g/ml.
