A3-m solution of vinegar (acetic acid and water) and a 3-m solution of salt water are both prepared. which has the greater molarity?

salt water and vinegar have equal molarities.

salt water will have the greater molarity because its molar mass is higher.

vinegar will have the greater molarity because its molar mass is higher.

it is impossible to determine with the information given.

The correct answer is :'Salt water and vinegar have equal molarities.'.

Explanation:

Molarity of the solution is defined as moles of compound present in the 1 liter volume of the solution.

We are given with 3 Molar solution of vinegar which means that 3 moles of acetic acid are present in 1 Liter solution of vinegar.

Also salt solution with 3 Molar concentration means that 3 moles of salt are o present in 1 Liter salt solution.

Molarity of acetic acid = Molarity of salt solution = 3 M

yes it is balanced

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
