The specific gravity of iron is 7.87, and the density of water at 4.00 ∘c is 1.00 g/cm3. you can use this information to find the density of iron. find the volume occupied by 4.50 g of iron.

The volume of iron occupied is

Explanation:

The relationship between specific gravity and density of a substance is given as:

Specific gravity of iron = 7.87

Density of water =

Putting values in above equation we get:

To calculate volume of a substance, we use the equation:

Density of iron =

Mass of iron = 4.50 g

Putting values in above equation, we get:

Hence, the volume of iron occupied is

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
