Question

нефть классифицируют на виды по содержанию серы.малосернистую(до 0,5%),сернистая(до 1,25 %),высокосернистая(до 2%).определите массу серы содержащейся в 45 тоннах каждого вида.

Answer 1

45 тонн= 45 000 кг-100%

т.е. малосернистой : 45*0,5/100= 225 кг.

сернистой :  45*1,25/100=562,5 кг.

высокосодержащей: 45*2/100= 900 кг

Answer 2

Classification of Oil Based on Sulfur Content

Oil is classified into different types based on its sulfur content. The three main classifications are:

1. Low-sulfur oil (up to 0.5% sulfur content) 2. Medium-sulfur oil (up to 1.25% sulfur content) 3. High-sulfur oil (up to 2% sulfur content)

Now, let's calculate the mass of sulfur contained in 45 tons of each type of oil.

Calculation of Sulfur Mass

1. Low-sulfur oil (up to 0.5% sulfur content): - Sulfur content: 0.5% (0.005) - Mass of low-sulfur oil: 45 tons - Mass of sulfur in low-sulfur oil: 0.005 * 45 = 0.225 tons

2. Medium-sulfur oil (up to 1.25% sulfur content): - Sulfur content: 1.25% (0.0125) - Mass of medium-sulfur oil: 45 tons - Mass of sulfur in medium-sulfur oil: 0.0125 * 45 = 0.5625 tons

3. High-sulfur oil (up to 2% sulfur content): - Sulfur content: 2% (0.02) - Mass of high-sulfur oil: 45 tons - Mass of sulfur in high-sulfur oil: 0.02 * 45 = 0.9 tons

Therefore, the mass of sulfur contained in 45 tons of each type of oil is as follows: - Low-sulfur oil: 0.225 tons - Medium-sulfur oil: 0.5625 tons - High-sulfur oil: 0.9 tons

Please note that these calculations are based on the given sulfur content percentages and the assumption that the sulfur content is evenly distributed throughout the oil.
