Hey There!:
The density is the quotient between the mass of a material and the volume occupied by it, The density can be expressed for a substance or for a mixture of substances. For example, water density in ambient conditions is equal to 1.00 g/cm3, which means that in 1 cm³ or 1 mL, there are 1.0 g of water. Therefore:
D = m / V
D = 20 g / 5 mL
D = 4,0 g/mL
hope that helps!
Answer:
Ali will need to either taste test or test the drinks on a ph scale. A neutral drink is water, as neutral has a ph of 7. The ph scale ranges from 1 to 14, going from acidic to basic. So if the drink has a ph less than 7, it is acidic, if its more, its basic.
