Answer: The molar mass of the given compound is 
Explanation:
In molecular formula of 
there are two chlorine atoms and one calcium atom.
The atomic mass of the calcium = 40.07 g/mol
The atomic mass of chlorine = 35.5 g/mol
Molar mass of the guven compound is :
The molar mass of the given compound is
Because this classification contrasts with that of crystalline solids whose atoms are arranged in a regular and orderly fashion forming crystalline networks.
Answer: it's easy just think about it:
Explanation:
weight: the weight of an object is the force acting on the object due to gravity.
mass: Mass is the amount of matter or substance that makes up an object.
in total: The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.

Answer:
9.14moles
Explanation:
Given parameters:
Number of atoms of butane = 5.5 x 10²⁴atoms
Unknown:
Number of moles = ?
Solution:
To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.
6.02 x 10²³ atoms makes up 1 mole of an atom
5.5 x 10²⁴ atoms will contain = 
= 9.14moles
c. the answer is radioactive elements are useful for dating materials
