Find the density of a sample with a mass of 2.56 g and a volume of 3.25 mL given that the formula for density is D = mass / volume.

The answer is 0.79 g/mL

Explanation:

The density of a substance can be found by using the formula

From the question

mass = 2.56 g

volume = 3.25 mL

We have

We have the final answer as

0.79 g/mL

Hope this helps you

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

The dispersed phase is liquid and dispersed medium in milk is liquid
