Apure gold metal bar displaces 0.82 l of water. what is the mass in kilograms? (the density of gold is 19.3 g/cm^3)

Mass of gold bar is 15.8 kg

Explanation:

The gold metal bar displaces volume of water equal to volume of metal bar.

So, volume of gold metal bar = 0.82 L

We know that density is the ratio of mass to volume.

So mass of gold bar = (density of gold)(volume of gold bar) = ()g =15826 g

Now, 1 g = 0.001 kg

So mass of gold bar  = () kg = 15.8 kg

answer; capital earns interest; entrepreneurship receives a profit or incurs a loss;

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
