What is the molarity of an acid that is made up of 9.5 moles of HCl dissolved in 1:24 L of water?

7.7 mol/L or M

Explanation:

Molarity is defined as moles of solute over litres of solution. So, in essence, Molarity= moles/litres

or often written as M=mol/L

Here we have 9.5 moles of HCl, and 1.24L of water so we just plug those in equation...

M= 9.5/1.24 = 7.7 mol/L or 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

i think it is true since you can test the answer and can use observations to complete it.
