Answer:
about 3.937
Explanation:
There are exactly 2.54 cm in an inch so we have
10cm/1 * 1inch/2.54cm = 10inch/2.54 = 3.937
Answer:
Oxygen (O), for example, has three naturally occurring isotopes, which can be written as 8/16O, 8/17 O, and 8/18O.
Explanation:
7 is atomic symbol 9 is atomic density 8 is the atomic number
Answer: The percent yield for the
is, 86.7 %
Explanation : Given,
Moles of
= 2.36 mol
Moles of
= 6.14 mol
First we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 2 moles of
react to give 6 moles of
So, 2.36 moles of
react to give
mole of
Now we have to calculate the percent yield for the
.
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
Therefore, the percent yield for the
is, 86.7 %
