One mole of n2 gas at stp will occupy what volume?

a.) 44.8 l
b.) 22.4 l
c.) 44.2 l
d.) 88.4 l
e.) none of the above

STP signifies standard temperature and pressure. This conditions are at 1 atmospheric pressure and 0 degrees Celsius. It has been said that at these conditions, one mole of a gas molecule is equivalent to 22.4 liters of volume. Therefore, the correct answer is option B. 

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
