Question

Мaca 0,3 см3 алюминия равна 0,81 г. Найдите массу 1 см3 алюминия.

Answer 1

Ответ:

Масса 2,7 грамм

Пошаговое объяснение:

0,3 см² = 0,81 грамм

1) 0,81/0,3=2,7 грамм

Answer 2

To find the mass of 1 cm^3 of aluminum, we can use the given information:

Maca = 0.3 cm^3 Mass of Maca = 0.81 g

Now, to find the mass of 1 cm^3 of aluminum (Maluminum):

Let's set up a proportion using the relationship between Maca and Maluminum:

Maca / Mass of Maca = Maluminum / 1 cm^3

Now, plug in the given values:

0.3 cm^3 / 0.81 g = Maluminum / 1 cm^3

To solve for Maluminum, cross-multiply:

Maluminum = (0.3 cm^3 * 1 cm^3) / 0.81 g Maluminum = 0.3 cm^3 / 0.81 g Maluminum ≈ 0.37037 g/cm^3

So, the mass of 1 cm^3 of aluminum is approximately 0.37037 grams.
