Question

У кілограмовому металевому зливку 700 г срібла. Решта маси - мідь. На скільки грамів більше у зливку срібла, ніж міді?

Answer 1

Масса меди 1000-700=300(г) т.е. меди меньше на 700-300=400(г)

Answer 2

Найдем количество меди в слитке 1000 г - 700 г = 300 г, на сколько больше серебра, чем меди 700 г - 300 г = 400 г, ответ: серебра больше на 400 г

Answer 3

Calculating the Difference in Mass between Silver and Copper in the Metal Ingot

To calculate the difference in mass between silver and copper in the metal ingot, we can use the given information that the ingot contains 700 g of silver and the rest of the mass is copper.

Step 1: Calculate the Total Mass of the Ingot The total mass of the ingot can be calculated by adding the mass of silver (700 g) to the mass of copper.

Step 2: Calculate the Mass of Copper To find the mass of copper, we subtract the mass of silver from the total mass of the ingot.

Step 3: Calculate the Difference in Mass Finally, we can calculate the difference in mass between silver and copper by subtracting the mass of copper from the mass of silver.

Let's proceed with the calculations.

Calculation

Step 1: Total Mass of the Ingot Total mass = Mass of silver + Mass of copper Total mass = 700 g + Mass of copper

Step 2: Mass of Copper Mass of copper = Total mass - Mass of silver Mass of copper = Total mass - 700 g

Step 3: Difference in Mass Difference in mass = Mass of silver - Mass of copper Difference in mass = 700 g - (Total mass - 700 g)

Now, let's calculate the difference in mass.

Result

The difference in mass between silver and copper in the metal ingot is 700 g.
