To solve this we assume
that the gas is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant temperature and number of moles of the gas
the product of PV is equal to some constant. At another set of condition of
temperature, the constant is still the same. Calculations are as follows:
P1V1 =P2V2
V2 = P1 V1 / P2
V2 = 153 x 3.00 / 203
<span>V2 = 2.26 L</span>

Answer:
64 moles
Explanation:
Let us begin by writing a balanced equation for the reaction. This is illustrated below:
2Na + Cl2 —> 2NaCl
From the equation above,
1 mole of Cl produced 2 moles of NaCl.
Therefore, 32 moles of Cl will produce = 32 x 2 = 64 moles of NaCl.
Therefore, 64 moles of NaCl are produced
