A piece of plastic has a mass of 14.2 grams and volume of 16.8cm cube. What is the mass of 1.00cm cube of this plastic?
Thanks for your help.
14.2 g _____16.8 cm3
_______________________ = 0.84 g ??????
1 cm3
To 3 significant figures I have 0.845 gt.
To find the mass of 1.00 cm³ of the plastic, we can use the given information about the mass and volume of the entire piece of plastic.
First, we can calculate the density of the plastic using the formula:
Density = Mass / Volume
Plugging in the given values:
Density = 14.2 grams / 16.8 cm³
Now, we can use the density to find the mass of 1.00 cm³ of the plastic. Since density is defined as mass per unit volume, we can rearrange the formula to solve for mass:
Mass = Density * Volume
Plugging in the calculated density and the volume of 1.00 cm³:
Mass = 14.2 grams / 16.8 cm³ * 1.00 cm³
Simplifying the equation:
Mass = 14.2 grams / 16.8
Now, calculating the mass:
Mass = 0.845 grams
Therefore, the mass of 1.00 cm³ of this plastic is 0.845 grams.
