A student finds that 15.13 mL of a liquid has a mass of 13.278 g. Determine the density of this liquid in g/mL - with the correct number of significant digits.

0.877g/ml

Explanation:

Density is calculated by dividing the mass of liquid by its volume

we have

mass = 13.278g

Volume = 15.13ml

density = 13.278g/15.13ml

= 0.877g/ml

we round the answer to four significant digits because there are only four digits in the denominator.

108

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.
