Answer:

#"Density"# #=# #"Mass"/"Volume"#

#rho_"titanium"~=4*g*cm^-3#

Explanation:

So all we have to do is calculate this quotient, and remember the formula for the volume of a sphere, #=4/3pir^3#

Now since #r=1.9/2*cm# (density is usually quoted as #g*mL# or #g*cm^-3#, at least by chemists it is...........)

#rho_"titanium"=m/V=(16.19*g)/(4/3pi(1.9/2*cm)^3)>=4*g*cm^-3#

Would this float on water? Why or why not?
