Convert 7.9 x 10^22 atoms of Ca to grams

Vika [28.1K]

Answer:

Mass = 5.24 g

Explanation:

Given data:

Number of atoms of Ca = 7.9×10²² atoms

Mass of Ca = ?

Solution:

First of all we will calculate the number of moles by using Avogadro number.

1 mole contain 6.022×10²³ atoms

7.9×10²² atoms × 1 mol /6.022×10²³ atoms

1.31 ×10⁻¹ mol

0.131 mol

Mass of Ca:

Mass = number of moles × molar mass

Mass = 0.131 mol × 40 g/mol

Mass = 5.24 g

Answer:

the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.

Decide which element probably has a boiling point most and least similar to the boiling point of cesium.

natka813 [3]

Answer:

Take a look at the attachment below

Explanation:

Take a look at the periodic table. As you can see, Rubidium is the closest element to Cesium, and happens to have the closest boiling point to Cesium, with only a difference of about 30 degrees.

Respectively, you would think that fluorine should have the least similarity to Cesium with respect to it's boiling point, considering it is the farthest away from the element out of the 4 given. This is not an actual rule, there are no fixed trends of boiling points in the periodic table, there are some but overall the trends vary. However in this case fluorine does have the least similarity to Cesium with respect to it's boiling point, a difference of about 1,546.6 degrees.
