3. how many grams in 18.7 mols of titanium?

895.11 g Titanium

Number of moles, n = Mass, m ÷ relative atomic mass

That is,

n = m ÷ R.A.M.

Therefore, to get the mass we would use, m = n × R.A.M.

In this case,

Number of moles, n = 18.7 moles

R.A.M of titanium = 47.867

Therefore,

Mass of titanium, m = 18.7 moles × 47.867

                                = 895.11 g

Therefore, 18.7 moles of titanium contains 895.11 g

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.
