Answer 1

Answer:

19.3

Explanation:

The relative density of gold is 19.3

Hope it may help u

Answer 2

✪✪$\huge{\underline\mathbb{SOLUTION!!...}}$

$\green{\underline\textbf{first calculate the loss in mass = 100g - 80g}}$

= 20g h2O displaced

$\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{\underline\textbf{</strong><strong>density</strong><strong> </strong><strong>of</strong><strong> </strong><strong>water</strong><strong> </strong><strong>=</strong><strong> </strong><strong>1</strong><strong>g</strong><strong>/</strong><strong>ml</strong><strong>}</strong><strong>}$

so, the object displaced 20 ml of water which equals the volume of the object...

with that, we can calculate the relative density when kept in water which equals...

$= \frac{mass}{volume}$

the object's relative density =

$\frac{80g}{20ml}$

$\</strong><strong>b</strong><strong>l</strong><strong>u</strong><strong>e</strong><strong>{\underline\textbf{</strong><strong>then</strong><strong> </strong><strong>the</strong><strong> </strong><strong>relat</strong><strong>ive</strong><strong> </strong><strong>density</strong><strong> </strong><strong>=</strong><strong> </strong><strong>4</strong><strong>g</strong><strong> </strong><strong>/</strong><strong> </strong><strong>ml</strong><strong> </strong><strong>}</strong><strong>}</strong><strong>$

if an object has the relative density greater than the liquid you are putting in it, then it will sink...

in this case, relative density of the object is 4g/ml which is greater than the water's density...

$\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{\underline\textbf{</strong><strong>then</strong><strong> </strong><strong>the</strong><strong> </strong><strong>obje</strong><strong>ct</strong><strong> </strong><strong>will</strong><strong> </strong><strong><u>sink</u></strong><strong>!</strong><strong>!</strong><strong>...}</strong><strong>}</strong><strong>$
