we have
8.4 mole N and 16.31 mole O.
Mole ratio:
N : O
8.4 : 16.31
or
8.4 / 8.4 : 16.31 / 8.4
or
1 : 1.94
or
1 : 2
thus
x = 1
and

3. Suppose you have X Binom(n, p) where n is known and p is unknown. Typically, people use p = _ to estimate p, where X = Xi is simply a sample of size l. This might represent simultaneously flipping n coins (just once!) and counting the number of heads you see, where each coin has Pheads - p. Now, if both n and p are known, we know the variance V of X is just np(1-p) If p is...
