Use the references to access imp a sample of hydrogen gas has a mass of 48.3 grams. how many h, molecules are there in the sample? molecules submit answer & next

The number of hydrogen molecules in the given amount is

Explanation:

To calculate the number of moles, we use the equation:

Given mass of hydrogen gas = 48.3 g

Molar mass of hydrogen gas = 2 g/mol

Putting values in above equation, we get:

According to mole concept:

1 mole of a compound contains number of molecules

So, 24.15 moles of hydrogen gas will contain = number of molecules.

Hence, the number of hydrogen molecules in the given amount is

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.
