Question

An empty jar weighs 1.43 lbs. How much will it weigh when 1.00 L of homogenized milk is poured into it? The density of homogenized milk is 1.03 g/mL. (1 lb=453.6 g)

Answer 1

First, convert the volume of the milk from liters to milliliters. Then, calculate the mass of the milk by multiplying the volume by the density. Finally, add the weight of the milk to the initial weight of the empty jar.

Step-by-step explanation:

To find the weight of the jar with the milk, we need to calculate the weight of the milk and add it to the initial weight of the empty jar. First, we need to convert the volume of the milk from liters to milliliters. Since 1 L = 1000 mL, the volume of 1.00 L of homogenized milk is 1000 mL. Next, we calculate the mass of the milk by multiplying the volume by the density:

Mass = volume x density

Mass = 1000 mL x 1.03 g/mL = 1030 g

Since 1 lb = 453.6 g, we can convert the mass of the milk from grams to pounds:

Mass in lbs = 1030 g x (1 lb/453.6 g) = 2.27 lbs

Finally, we add the weight of the milk to the initial weight of the empty jar:

Total weight = 1.43 lbs + 2.27 lbs = 3.70 lbs
