A chemist wants to make 1.5 L of 0.5M HBr by diluting a 6.OM HBr solution. Hon many liters of that solution should be used?

Answer : The volume of HBr solution used should be, 0.125 L.

Explanation :

Formula used :

where,

are the molarity and volume of HBr solution.

are the molarity and volume of diluted HBr solution.

We are given:

Putting values in above equation, we get:

Therefore, the volume of HBr solution used should be, 0.125 L.

yes they ca   is ur ansswerrr

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.
