What is the volume v of a sample of 4.00 mol of copper? the atomic mass of copper (cu) is 63.5 g/mol, and the density of copper is 8.92×103kg/m3. express your answer in cubic centimeters to 3 significant figures.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

v 154.9= 0.9 length length s little over 154.9cm

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
