Question

Ваза масой 2400 г зделана из золота миди олова жилеза золота в вазе 61/120 от масы всево сплава меди 19/61 от масы золота а олова 29/61 йот масы золота какая маса жилеза в вазе

Answer 1

Масса вазы = 2400г
Золота =61/120 от 2400г
Меди =19/61 от золота
Олова = 29/61 от золота
Масса железа = ?
------------------------------------
Решение:
1) 2400 * 61/120 = 1220 (г) золота в сплаве
2) 19/61 + 29/61 = 48/61 всего меди и олова
3) 1220 * 48/61 = 960 (г) меди и олова в сплаве
4) 1220 + 960 = 2180 (г) золота, меди и олова в сплаве
5) 2400 - 2180 = 220 (г) железа
Ответ: 220 г железа в сплаве.

Answer 2

Calculating the Mass of Iron in the Vase

To calculate the mass of iron in the vase, we can use the given information about the composition of the alloy and the total mass of the vase.

Given: - Total mass of the vase = 2400 g - Composition of the alloy: - Gold: 61/120 of the alloy's mass - Copper: 19/61 of the mass of gold - Tin: 29/61 of the mass of gold

We need to find the mass of iron in the alloy.

Calculations

First, let's find the mass of gold, copper, and tin in the alloy.

1. Mass of Gold: \[ \text{Mass of Gold} = \frac{61}{120} \times \text{Total mass of the vase} \]

2. Mass of Copper: \[ \text{Mass of Copper} = \frac{19}{61} \times \text{Mass of Gold} \]

3. Mass of Tin: \[ \text{Mass of Tin} = \frac{29}{61} \times \text{Mass of Gold} \]

Now, we can find the mass of iron in the alloy by subtracting the combined mass of gold, copper, and tin from the total mass of the vase.

4. Mass of Iron: \[ \text{Mass of Iron} = \text{Total mass of the vase} - (\text{Mass of Gold} + \text{Mass of Copper} + \text{Mass of Tin}) \]

Let's calculate these values.
