Question

Помогите пожалуйста забыл как решать ??? В эбонитовой пластмассе содержится 60% каучука,остальное - сера. На сколько граммов больше каучука ,чем серы содержится в 320 г эбонитовой пластмассе.

Answer 1

320 г ----- 100%
каучука ----- 60%
каучука -- 320*60/100 = 32*6 = 192 г
остальное сера -- 320 - 192 = 128 г
192 - 128 = 64 г --- на столько каучука больше))

Answer 2

Calculating the Amount of Rubber and Sulfur in Ebonite Plastic

To calculate the amount of rubber and sulfur in 320 grams of ebonite plastic, we can use the given information that the ebonite plastic contains 60% rubber and the rest is sulfur.

Step 1: Calculate the Amount of Rubber To find the amount of rubber in 320 grams of ebonite plastic, we can use the fact that 60% of the ebonite is rubber. We can calculate this as follows:

320 grams * 60% = 320 grams * 0.60 = 192 grams of rubber in 320 grams of ebonite plastic.

Step 2: Calculate the Amount of Sulfur Since the remaining percentage (100% - 60% = 40%) of the ebonite is sulfur, we can calculate the amount of sulfur in 320 grams of ebonite plastic as follows:

320 grams * 40% = 320 grams * 0.40 = 128 grams of sulfur in 320 grams of ebonite plastic.

Step 3: Find the Difference To find the difference between the amount of rubber and sulfur in 320 grams of ebonite plastic, we subtract the amount of sulfur from the amount of rubber:

192 grams (rubber) - 128 grams (sulfur) = 64 grams

Conclusion: Therefore, there are 64 grams more rubber than sulfur in 320 grams of ebonite plastic.

This calculation is based on the given information that the ebonite plastic contains 60% rubber and the rest is sulfur
