1 mol zn ------------- 6.02x10²³ atoms
4.4 mol -------------- ??
4.4 x ( 6.02x10²³ ) / 1 => 2.648x10²⁴ atoms of zn
A gas is something that takes up the space of the container, because it doesn't have a fixed shape.
Answer:
vascular plants have that absorb the water and mineral from the air
The question is incomplete. The complete question is :
Hydrogen
gas and oxygen
gas react to form water vapor
. Suppose you have 11.0 mol of
and 13.0 mol of
in a reactor. Calculate the largest amount of
that could be produced. Round your answer to the nearest 0.1 mol .
Solution :
The balanced reaction for reaction is :

11.0 13.0
11/2 13/1 (dividing by the co-efficient)
6.5 mol 13 mol (minimum is limiting reagent as it is completely consumed during the reaction)
Therefore,
is limiting reagent. It's stoichiometry decides the product formation amount from equation above it is clear that number of moles for
will be produced = number of moles of 
= 11.0 mol
