Answer:

B. mass, volume

Explanation:

Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.

Answer: Option (B) is the correct answer.

Explanation:

Density of a substance is defined as mass divided by its volume.

Mathematically,         Density = \frac{mass}{volume}

So, density is proportional to the mass of substance. Hence, an increase in mass will lead to increase in density of the substance also.

Whereas density is inversely proportional to volume of a substance. Hence, an increase in volume will lead to a decrease in density of the substance.

Therefore, we can conclude that density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.

Which formula can be used to express the law of conservation of momentum, where p = momentum? pi = pf pi > pf pi < pf pi ≠
Len [333]
<h2>Answer:</h2>

The correct option is Pf = Pi

<h2>Explanation:</h2>

Momentum is the product of velocity and mass of an object. It is a physical quantity and the law of conservation of momentum says that for a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. So simply it means that Pf = Pi.

How many atoms are in 4.6 mol K?
Fudgin [204]

Answer:

27.7  × 10²³ atoms

Explanation:

Given data:

Number of moles of Potassium = 4.6 mol

Number of atoms = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 4.6 moles of K:

One mole = 6.022 × 10²³ atoms

4.6 mol × 6.022 × 10²³ atoms= 27.7  × 10²³ atoms
