How many grams of nitrogen trihydride can be dissolve in 200g of water at 25°c

clouds form

solid ice forms on leaves.

water droplets form on grass.

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

they are all solids.
