Two liquids of A and B have densities of 1.44g/cm^3 and 1.48g/cm^3 respectively. If 25cm^3 of each liquid is added in a flask what would be the mass of the liquid in the flask?

Also will a 5ml pipette always deliver the same value?
Thanks.

anonymous · Answer

mass (m) = density (ρ) * volume (V)
If you look at the units for each you will understand this, 
g/cc * cc = g

To your second question, it will deliver the same volume of 5mL=5cc but it will not give the same mass for substances of different densities, as above for example with a 25mL pipette
