The density of a certain type of plastic is 0.66 g/cm3. If a sheet of this plastic is 10.0 m long, 1.0 m wide, and 1 cm thick, what is its mass?
Enter your answer in scientific notation.
1E3 * 1E2 * 1 *0.66 = 6.6E4 g/cm^3
oops ... just 6.6E4 g ... no cm^3
To find the mass of the plastic sheet, you can use the following formula:
Mass = Density x Volume
First, let's calculate the volume of the plastic sheet using the given dimensions:
Volume = length x width x thickness
Volume = 10.0 m x 1.0 m x 0.01 m
Volume = 0.1 m^3
Now we can calculate the mass using the density:
Mass = 0.66 g/cm^3 x 0.1 m^3
To convert the units, we need to know the conversion factor between grams and kilograms (since the SI unit for mass is kilogram):
1 kilogram (kg) = 1000 grams (g)
To convert grams to kilograms, we divide by 1000:
Mass = (0.66 g/cm^3 x 0.1 m^3) / 1000
Mass = 0.0066 kg
Now we can write the answer in scientific notation:
Mass = 6.6 x 10^-3 kg
Therefore, the mass of the plastic sheet is 6.6 x 10^-3 kg.
