Question

Стакан вмещает 250 грамм воды. Найти массу, налитой в стакан меди. Помогите пожалуйста.

Answer 1

Дано:
m в = 0,25 кг
p в = 1000 кг/м³
p м = 8900 кг/м³
Найти: m м - ?
Решение:
V в = V м = V
V = m/p
V = 0,25 кг/1000 кг/м³ = 0,00025 м³
m м = pмV 
m м = 8900 кг/м³ × 0,00025 м³ = 2,225 кг

Answer 2

Calculation of the Mass of Copper in the Glass

To find the mass of copper in the glass, we need to know the volume of copper in the glass and the density of copper. However, the information provided in the question does not specify the volume or density of copper. Therefore, it is not possible to calculate the mass of copper in the glass without this additional information.

If you can provide the volume or density of copper, I would be happy to help you calculate the mass.
