Question

Using a mass of 1.8 g and the volume displaced by the sample, calculate the sample's density. A) 0.17 g/mL B) 0.35 g/mL C) 0.60 g/mL D) 0.78g/mL

Answer 1

The answer to that probably would be C excuse me if I am wrong.

Answer 2

Answer:

Explanation:

The density of any element is calculated as:

$d=\frac{m}{v}$

Were d= density, m= mass and v=volume. Since we doesn't know the volume, lets do the calculation of the volume displaced for each option (a, b,c,d)

Clear m from the previous equation, so we have:

$v=\frac{m}{d}$

for a)

$v=\frac{1.8}{0.17} =10.58 mL$

for b)

$v=\frac{1.8}{0.35} =5.14 mL$

for c)

$v=\frac{1.8}{0.6} =3 mL$

for d)

$v=\frac{1.8}{0.78} =2.3mL$

So, just compare the given volume displaced match it with your density and that is the answer.
