determine the density g/mL for a plastic material weighs 2.68 lb and has a volume of 3.5 L
2.68lb/3.5L * 454g/lb * 1L/1000mL = ____ g/mL
To determine the density of the plastic material, you need to convert the weight from pounds (lb) to grams (g) and the volume from liters (L) to milliliters (mL).
Step 1: Convert the weight from pounds to grams (1 lb = 453.59237 g).
Weight in grams = 2.68 lb * 453.59237 g/lb
Step 2: Convert the volume from liters to milliliters (1 L = 1000 mL).
Volume in mL = 3.5 L * 1000 mL/L
Step 3: Calculate the density by dividing the weight in grams by the volume in milliliters.
Density = Weight in grams / Volume in mL
Now let's calculate the density.
Weight in grams = 2.68 lb * 453.59237 g/lb
Weight in grams = 1214.47131696 g
Volume in mL = 3.5 L * 1000 mL/L
Volume in mL = 3500 mL
Density = Weight in grams / Volume in mL
Density = 1214.47131696 g / 3500 mL
Therefore, the density of the plastic material is approximately 0.347 g/mL.
To determine the density of a plastic material, you need to divide the weight of the material by its volume.
Given:
Weight = 2.68 lb
Volume = 3.5 L
First, let's convert the weight from pounds (lb) to grams (g) since the volume is given in liters (L) and the standard unit of density is grams per milliliter (g/mL).
1 lb = 453.592 g (approximately)
Therefore, 2.68 lb = 2.68 * 453.592 g ≈ 1215.217 g
Now, we can calculate the density:
Density = Weight / Volume
Density = 1215.217 g / 3.5 L
To get the density in g/mL, we need to convert the volume from liters to milliliters. Since 1 L equals 1000 mL, we multiply the volume by 1000:
Density = 1215.217 g / (3.5 L × 1000 mL/L)
Density = 1215.217 g / 3500 mL
Density ≈ 0.347 g/mL
Therefore, the density of the plastic material is approximately 0.347 g/mL.
