Calculate the molarity of 1.60L of a solution containing 1.55g of dissolved KBr

the molarity is .00814

Explanation:the formula for molarity is moles over liters but we have grams so we do given over one so 1.55 over 1 multiplied by 1/119.0023 which is tht two atomc masses addes together then you get the moles and divde them by the liters to get the molarity hope this helps god bless

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.
