Question

В состав железного метеорита входит 91% железа и 8 1/3 % никеля. Сколько кг железа , сколько кг никеля входит в состав Сихотэ-Алинского железного метеорита, масса которого 51 кг ?

Answer 1

1) 51*91:100=46,41 кг железа
2) 5*8 1/3:100=8*25/3:100=2/3 кг никеля   

Answer 2

Calculating the Composition of the Sikhote-Alin Iron Meteorite

To calculate the amount of iron and nickel in the Sikhote-Alin iron meteorite, we can use the given composition percentages and the total mass of the meteorite.

Given: - Iron composition: 91% - Nickel composition: 8 1/3% (or 8.33%)

Total mass of the meteorite: 51 kg

Calculating the Amount of Iron:

To find the amount of iron in the Sikhote-Alin iron meteorite, we can use the given iron composition percentage.

Amount of Iron = (Iron Composition / 100) * Total Mass

Amount of Iron = (91 / 100) * 51 kg

Amount of Iron = 0.91 * 51 kg

Amount of Iron = 46.41 kg

Calculating the Amount of Nickel:

To find the amount of nickel in the Sikhote-Alin iron meteorite, we can use the given nickel composition percentage.

Amount of Nickel = (Nickel Composition / 100) * Total Mass

Amount of Nickel = (8.33 / 100) * 51 kg

Amount of Nickel = 0.0833 * 51 kg

Amount of Nickel = 4.25 kg

Conclusion:

Therefore, in the Sikhote-Alin iron meteorite with a mass of 51 kg, there are approximately 46.41 kg of iron and 4.25 kg of nickel.
