Question

Решите задачу Сплав из свинца и олова содержит 1.52 кг свинца и 0.76 кг олова. В каком отношении взяты свинец и олово? какую часть сплава (По массе) составляет олово и какую часть свинец ?

Answer 1

Свинец-1,52кг
Олово-0,76

Отношение свинца к олову : 1,52:0,76=2, значит о ношение равно 2:1,
1,52+0,76=2,28 кг (общая масса сплава)
1,52:2,28=152/228=2/3(часть свинца )
0,76:2,28=76/228=1/3(часть олова)

Answer 2

Task Solution:

To solve this problem, we need to find the ratio in which lead and tin are taken and then determine the proportion of the alloy that is composed of lead and tin.

Let's start by finding the ratio of lead to tin in the alloy.

Step 1: Find the Ratio of Lead to Tin:

The alloy contains 1.52 kg of lead and 0.76 kg of tin. To find the ratio, we can divide the mass of lead by the mass of tin: Lead : Tin = 1.52 kg : 0.76 kg

This simplifies to: Lead : Tin = 2 : 1

So, the lead and tin are taken in the ratio of 2:1.

Step 2: Determine the Proportion of Lead and Tin in the Alloy:

Now, let's determine the proportion of the alloy that is composed of lead and tin.

The total mass of the alloy is 1.52 kg (lead) + 0.76 kg (tin) = 2.28 kg.

Proportion of Lead:

Lead makes up 1.52 kg out of 2.28 kg, so the proportion of lead in the alloy is:

Lead proportion = (1.52 kg / 2.28 kg) * 100% = 66.67%

Proportion of Tin:

Similarly, tin makes up 0.76 kg out of 2.28 kg, so the proportion of tin in the alloy is:

Tin proportion = (0.76 kg / 2.28 kg) * 100% = 33.33%

Therefore, the alloy is composed of approximately 66.67% lead and 33.33% tin by mass.

Conclusion:

The lead and tin are taken in the ratio of 2:1, and the alloy consists of approximately 66.67% lead and 33.33% tin by mass.
