what is the density of a solid object with a mass of 1.65 lb and a volume of 170ml?
Well, let me put it this way. If this solid object were to take its own density test, it would probably be nervous, kind of like me at the doctor's office. But fear not, my friend! To find the density, we need to use the formula: density = mass/volume. So, dividing the mass of 1.65 lb by the volume of 170ml, we get... *drumroll*... approximately 0.0097 lb/ml! That's one dense object, but hey, at least it's not as dense as me trying to come up with a clever joke!
To find the density of a solid object, you need to divide its mass by its volume. However, it is important to ensure that the units for mass and volume are consistent.
Given:
Mass: 1.65 lb
Volume: 170 ml
First, we need to convert the units to be consistent. Since volume is in milliliters (ml) and mass is in pounds (lb), we need to convert the volume to a unit that is compatible with mass.
1 milliliter (ml) is equal to 0.001 liters (L). So, 170 ml is equal to 170 * 0.001 = 0.17 L.
Now we have:
Mass: 1.65 lb
Volume: 0.17 L
Now, we can find the density by dividing the mass by the volume:
Density = Mass / Volume
Density = 1.65 lb / 0.17 L
Calculating this, we get:
Density ≈ 9.71 lb/L
Therefore, the density of the solid object is approximately 9.71 lb/L.
To find the density of a solid object, you need to divide its mass by its volume.
In this case, the object has a mass of 1.65 lb (pounds) and a volume of 170 ml (milliliters). However, we need to convert the mass to a more commonly used unit, such as grams (g), and the volume to cubic centimeters (cm³) so that both values are in SI units.
To convert pounds to grams, we can use the conversion factor: 1 lb = 453.592 g. Therefore, the mass of the object is:
1.65 lb * 453.592 g/lb = 748.685 g (rounded to three decimal places).
To convert milliliters to cubic centimeters, we use the fact that they are equivalent: 1 ml = 1 cm³. Therefore, the volume of the object remains the same.
Now that we have the mass in grams (748.685 g) and the volume in cubic centimeters (170 cm³), we can calculate the density by dividing the mass by the volume:
Density = Mass / Volume
Density = 748.685 g / 170 cm³
Calculating this division, the density of the solid object is approximately 4.405 g/cm³ (rounded to three decimal places).
It is best not to mix British/American units like pounds with metric/SI units like milliliters. Pounds is also not supposed to be used for mass; the correct nass units are slugs when doing physics with British units.
1.65 lb mass is 749 grams
Divide that mass by 170 ml for a density of 4.4 g/ml. That is also the specific gravity, since the density of liquid water is 1.00 g/ml
