How many moles if mgcl2 are there in 340g of the compound?

Hi!

The answer would be ~ 3.58

You will need to use the simple formula of finding the number of moles, given the mass of the compound, which is:

number of moles of compound = mass of compound / Mr of compound

The mass in this equation is the mass of the compound you have/ are considering.

The Mr is the sum of the atomic masses of each element in the compound.

To proceed with this, you need to have two of the following values:

Mass : 340g

Mr of MgCl2 : 95

Number of moles : ?

Substituting the respective values in the equation:

number of moles = mass / Mr

number of moles = 340 / 95

number of moles = 3.58

Hope this helps!

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
