Answer:
We are in Tropical Rainforests.
Explanation:
Biome is basically an ecological region of earth that has specific type of flora and fauna (plants and animals). Every biome has specific abiotic factors like specific climate, temperature, geology, vegetation, soils and relief.
There are total 8 biomes in the world
- Desert
- Grassland
- Temperate Boreal Forest  
- Chaparral
- Tropical Savanna
- Tropical Rainforest
- Tundra
- Temperate Deciduous Forest
Now in our question, we have been given some conditions and are asked to identify the biome. The annual precipitation is about 300 cm and the average temperature is around 25 degrees Celsius.
Now, if we study the characteristics of all these biomes, it is very simple to identify that the biome is Tropical Rainforest.
Important characteristics of Tropical Rainforest:
- They receive more than 200 cm of rain each year.
- The temperature of the biome is between 20 degree Celsius and 25 degree Celsius during the whole year.
- Around 50 percent of the animal specie of the world are found here.

Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
 
        
             
        
        
        
The conversion of volume to moles at STP is 1 mole.
The ideal gas equation is given as :
P V = n R T 
where, 
P = pressure of the gas 
V = volume of the gas
n = ?
R = constant = 0.823 atm L / mol K
T = temperature 
At STP , the pressure is 1 atm and the temperature is 273.15 K, the volume At STP is 22.4 L.
moles , n = P V / R T 
n = ( 1 × 22.4 ) / (0.0823 × 273.15)
n = 1 mole 
Thus, at STP , the number of moles is 1 mol.
