Calculation of Sulfur Content in Soft Rubber and Ebonite

To calculate the amount of sulfur in soft rubber and ebonite, we need to know the mass of the substances and their respective sulfur percentages.

Given: - Sulfur content in soft rubber: 2% - Sulfur content in ebonite: 32%

We need to find: a) The amount of sulfur in soft rubber b) The amount of sulfur in 3 kg of ebonite

Calculation for Soft Rubber:

To find the amount of sulfur in soft rubber, we need to know the mass of the soft rubber. Unfortunately, the mass of the soft rubber is not provided in the question. If you can provide the mass of the soft rubber, I can help you calculate the amount of sulfur in it.

Calculation for Ebonite:

To find the amount of sulfur in 3 kg of ebonite, we can use the sulfur percentage given for ebonite.

The amount of sulfur in ebonite can be calculated using the following formula:

Amount of sulfur in ebonite = (Sulfur percentage in ebonite / 100) * Mass of ebonite

Substituting the given values: - Sulfur percentage in ebonite = 32% - Mass of ebonite = 3 kg

Amount of sulfur in ebonite = (32 / 100) * 3 kg

Calculating the above expression: Amount of sulfur in ebonite = 0.32 * 3 kg = 0.96 kg

Therefore, the amount of sulfur in 3 kg of ebonite is 0.96 kg.

Please provide the mass of the soft rubber if you would like to calculate the amount of sulfur in it.
