Question

ДАМ 12 БЛ. При анализе старинного кольца массой 3,34г было выяснено, что оно на 94,5% состоит из серебра, остальное- примеси других металлов. Рассчитайте массу примесей в старинном кольце.

Answer 1

100-94.5=5.5%
3.34·5.5÷100=0.1837g

Answer 2

Calculation of the Mass of Impurities in the Antique Ring

To calculate the mass of impurities in the antique ring, we need to know the total mass of the ring and the percentage of silver it contains.

Given: - Total mass of the ring: 3.34 g - Silver content: 94.5%

To find the mass of impurities, we can subtract the mass of silver from the total mass of the ring.

Step 1: Calculate the mass of silver in the ring. To find the mass of silver, we multiply the total mass of the ring by the percentage of silver content: Mass of silver = Total mass of the ring * (Percentage of silver / 100)

Mass of silver = 3.34 g * (94.5 / 100) = 3.34 g * 0.945 = 3.15 g

Step 2: Calculate the mass of impurities. To find the mass of impurities, we subtract the mass of silver from the total mass of the ring: Mass of impurities = Total mass of the ring - Mass of silver

Mass of impurities = 3.34 g - 3.15 g = 0.19 g

Therefore, the mass of impurities in the antique ring is 0.19 grams.
