Answer:
- Density Liquid = 0.841 g/mL
- Density Metal = 2.711 g/cm³
Explanation:
- The density of the liquid is:
Mass Liquid / Volume Liquid
From the problem we know that Volume Liquid = 25.0 mL, <u>the mass of the liquid can be calculated by substracting masses</u>:
- Mass Liquid + Mass Slug + Mass Empty Cylinder = 125.934 g
- Mass Liquid + 15.454 g + 89.450 g = 125.934 g
- Mass Liquid = 125.934 g - 15.454 g - 89.450 g
Thus the density of the liquid is:
Density Liquid = 21.030 g / 25.0 mL = 0.841 g/mL
2. The density of the metal slug is:
Mass Metal / Volume Metal
We already know that the mass of the slug is 15.454 g. Its volume can be calculated using <em>Archimede's principle</em>, which states that the volume of an object is equal to the volume of liquid it displaces, in other words:
Volume Metal = 30.7 mL - 25.0 mL = 5.7 mL
Thus the density of the metal slug is
Density Metal = 15.454 g / 5.7 mL = 2.711 g/mL = 2.711 g/cm³
Answer:
7g/cm³
Explanation:
Given parameters:
Mass of the mineral = 21g
Volume = 3cm³
Unknown:
Density of the mineral = ?
Solution:
Density of a substance is the mass per unit volume of the substance.
Density =
Now insert the given parameters and solve;
Density = = 7g/cm³
The mineral with a density of 7g/cm³ is Galena, an ore of lead.
the answer is g the energy from the sun evaporates the water along with condition forming the clouds. <span />
Answer:
Chemical fertilizer impact the environment by the following ways:
- Their overuse hardened the soil
- It causes soil pollution.
- It decreases fertility of the soil and strengthen pesticides.
When the sun becomes active, the occurrences of phenomena such as solar flares, coronal mass ejection become frequent. The amount of high-energy particles and extreme shortwave radiation released, such as X-rays and UV, will also increase. These phenomena affect the ionosphere of the Earth's atmosphere the most.
