Which statements about freshwater sources are true? Check all that apply. O Only about 3 percent of Earth's water ís fresh water.
O Most of the fresh water on Earth is groundwater.
O About 75 percent of the fresh water on Earth is frozen in ice sheets.
O The largest source of usable fresh water is groundwater.
O More fresh water is in the atmosphere than in rivers and lakes.

Only about 3% of the water in the Earth is fresh water and about 75 % of the fresh water on Earth is frozen in ice sheets.  

•The most vital element present on the Earth is water. All the living beings are dependent on it.  

•Water is present in the majority of the Earth, however, of this only 3% of the water is freshwater, the rest is saline and undrinkable.  

•Of this 3%, the 75 percent of the freshwater is present in the form of ice and glaciers in the polar region.  

•The remaining 24 percent is the groundwater and the rest 1 percent includes the waters of rivers, lakes, and ponds.

Explanation:

1 is true

2 is false

3 is true

4 is true

5 is false

That is what I got from researching.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
