<em>D</em> = 0.9570 g/mL
Mass of mixture = 88.219 g – 40.368 g = 47.851 g
<em>D</em> = mass/volume = 47.851 g/50.00 mL = 0.9570 g/mL
Answer:
Approximately
.
Explanation:

The actual yield of
was given. The theoretical yield needs to be calculated from the quantity of the reactant.
Balance the equation for the hydrolysis of water:
.
Note the ratio between the coefficient of
and
:
.
This ratio will be useful for finding the theoretical yield of
.
Look up the relative atomic mass of hydrogen and oxygen on a modern periodic table.
Calculate the formula mass of
and
:
.
.
Calculate the number of moles of molecules in
of
:
.
Make use of the ratio
to find the theoretical yield of
(in terms of number of moles of molecules.)
.
Calculate the mass of that approximately
of
(theoretical yield.)
.
That would correspond to the theoretical yield of
(in term of the mass of the product.)
Given that the actual yield is
, calculate the percentage yield:
.
Answer:
The light bends
Explanation:
When it passes through two different densities it changes directions, causing a bend
