How many molecules are in 2.50 moles of carbon dioxide?
podryga [215]

Answer:

1.5055×10²⁴ molecules

Explanation:

From the question given above, the following data were obtained:

Number of mole CO₂ = 2.5 moles

Number of molecules CO₂ =?

The number of molecules present in 2.5 moles CO₂ can be obtained as:

From Avogadro's hypothesis,

1 mole of CO₂ = 6.022×10²³ molecules

Therefore,

2.5 mole of CO₂ = 2.5 × 6.022×10²³

2.5 mole of CO₂ = 1.5055×10²⁴ molecules

Thus, 1.5055×10²⁴ molecules are present in 2.5 moles CO₂

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options:
Marrrta [24]

Answer:

True

Explanation:

The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.

  • Electromagnetic waves are waves that do not require a material medium for their propagation.
  • They are able to pass through vacuums and mediums with particles at constant speed.
  • It is mechanical waves whose speed is medium dependent.
  • Mechanical waves have varying speed based on the mediums they move through.

If 23.5 g of magnesium occupies 13.5 cm^3 what is the density of magnesium
lara31 [8.8K]

The density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³

<h3>What is Density ?</h3>

Density is the measurement of how tightly a material is packed together.

It is defined as the mass per unit volume.

Given ;

  • Mass = 23.5 g
  • Volume = 13.5 cm³

Formula to calculate density ;

Density = mass / volume

             =23.5 / 13.5 = 1.74 g/cm³

Hence, the density of magnesium will be 1.74 g/cm³ if 23.5 g of magnesium occupies 13.5 cm³.
