How many moles of titanium are in a sample containing 2.8 x 10^24 atoms? 1) 1.69 x 10^48
2) 4.65 x 10^43
3) 4.65
4) 0.0465
5) 48

4.65 moles

Explanation:

To calculate this, we can use Avogradro's Number: 6.022*10^23

So, there are 4.65 moles in 2.8*10^24 atoms of Ti

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
