Question:

A student measures the mass of an #8# #cm^3# block of brown sugar to be 12.9 g. What is the density of the brown sugar?

Answers

#rho="mass"/"volume"#, here #rho~=1.6*g*cm^-3#

Explanation:

#"Density"#, #rho#, is mass per unit volume and is thus defined as the quotient, #"mass"/"volume"#, and typically chemists use units of #g*cm^-3# or #g*mL^-1#.

And here this quotient is...........

#(12.9*g)/(8*cm^3)#; does this give the required units?

Note that #1*cm^3-=1*mL......#
