Answer:
Difference between Homogeneous mixture and Heterogeneous Mixture are as follows:
- A mixture or sample that is consist of uniform composition and properties is called a homogeneous mixture while a mixture or sample that is consist of different composition and properties is called a heterogeneous mixture.
- Homogenous mixture has only single phase while heterogeneous mixture has two or more phases.
- Homogenous mixture can not be separated by physical methods while heterogeneous mixture can be separated out physically.
- Example of homogenous mixture is Water and sugar and heterogeneous mixture is oil and water.
The percentage of the mass of cellulose can be calculated by dividing the mass of the mass of cellulose in the sample by the total mass of the sample and then multiplying the output by 100 to get the percentage.
Mass of cellulose in sample = 0.38 grams
Total mass of sample = 3.35 + 0.38 + 8.76 = 12.49 grams
mass percent of cellulose = (0.38/12.49) x 100 = 3.0424%
