What will be the number of atoms in 0.750 gram of Fe

Chemistry
1 answer:
expeople1 [14]4 years ago
3 0

Answer:

8.085x10²¹ atoms

Explanation:

Atomic mass of Fe = 55.845 g/mol

it means ,

1 mole Fe = 55.845 g

1 mole = 6.02x10²³  atoms

so,

55.845g Fe has = 6.02x10²³ atoms

∴0.750 g  Fe has = {(6.02x10²³ x 0.750)/55.84} atoms

                             =8.085x10²¹ atoms

Anybody know chemistry Grahams law ?
sukhopar [10]
There is two different types but i’ll just do both meanings just incase.

Graham's Law of Diffusion: the rate of diffusion of one gas through another is inversely proportional to the square root of the density of the gas.

Graham's Law of Effusion: the rate of effusion of a gas is inversely proportional to the square root of the density of the gas.

hopes this helps..!

What volume of water has the same mass as 9.0m3 of ethyl alcohol?
Triss [41]
This question requires the knowledge of density. 

The density of ethyl alcohol = 789 kg m⁻³
The density of water = 1000 kg m⁻³

Density = Mass / Volume 

By applying ethyl alcohol,
    789 kg m⁻³ = Mass / 0.9 m³
         Mass     = 710.1 kg
hence the mass of 0.9 m³ ethyl alcohol is 710.1 kg.

Then by applying water,
     1000 kg m⁻³ = 710.1 kg / Volume
      Volume        = 0.7101 m³
                          = 0.7 m³
hence the equal water volume is 0.7 m³

A hydroelectric dam produces renewable energy for the local area. Which best explains why more hydroelectric dams are not built?
romanna [79]

Answer:

The dam disrupts the river wildlife and ecosystem.

Explanation:

Though it is believed that using the dam as a power generation or hydroelectric power supply generates no greenhouse gases, it, however, has many disadvantages which make it deemed not suitable or sustainable for use in the contemporary time.

Majorly, the top reason why more hydroelectric dams are not built is that "the dam disrupts the river wildlife and ecosystem."

Also, it affects the water quality and other use of water for humans such as recreational use.

There is also a possible chance of dams producing methane; a greenhouse gas through the organic materials in the water that is rotting.
