Answer : 0.5 moles of oxygen are completely consumed in the production of 1.00 mole of Na_2O

Solution : Given,

Moles of Na_2O = 1 mole

The given balanced reaction is,

4Na+O_2\rightarrow 2Na_2O

From this balanced reaction, we conclude that

As, 2 moles of Na_2O produces from 1 moles of O_2

So, 1 mole of Na_2O produces from \frac{1}{2}=0.5 moles of O_2

Therefore, 0.5 moles of oxygen are completely consumed in the production of 1.00 mole of Na_2O

The answer is 0.5 moles because if 1 moles of o2 is consumed to produce 2 moles of Na2O, then 0.5 moles of o2 will be consumed to produce 1 mole of Na2O.<span />

Calculate the mass of grams of 14.79ml of a substance. It'd density is 1.193gml
Alisiya [41]
<span>D=m/v

Given:
d=1.193g/ml
v= 14.79ml

Solution
m=dv
m=1.193g/ml x 14.79ml

m= 17.644g

Density is the mass per volume of the material. Basically, it refers to the measurement of how crammed together is the matter. The formula to calculate density is rho = m/v wherein rho is the density, m stands for the mass and v stands for the volume.</span>

If 4.5 moles of AlCl3 were made, how many moles of CuCl2 were used?
Troyanec [42]

Answer:

6.75 moles of CuCl₂ were used

Explanation:

Given data:

Number of moles of AlCl₃ formed = 4.5 mol

Number of moles of CuCl₂ used = ?

Solution:

Chemical equation:

3CuCl₂ + 2Al  →   2AlCl₃ + 3Cu

Now we will compare the moles of CuCl₂ and AlCl₃

               AlCl₃       :      CuCl₂

                   2         :        3

                 4.5        :      3/2×4.5 = 6.75

6.75 moles of CuCl₂ were used.
