Asample of 76 g of nacl is dissolved to make 1 l of solution. what is the molarity of the solution? show your work.

1.3005 M

Explanation:

Given that,

Mass of NaCl =

Molar mass of NaCl=

The formula for calculation of moles,

Moles,

Given that volume

Molarity,

Therefore the molarity is 1.3005 M.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
