I think the answer is D. Bonds
10 moles because for every one mile of oxygen, O2 , you produce 2 miles of water , H20 and therefore if you have 5 moles of oxygen.. you produce moles of water
Answer:
The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a metre (0.000000001 m).
Answer:
N2O4
Explanation:
To obtain the molecular formula of the compound, first, let us calculate the empirical formula for the compound. This is illustrated below:
N = 0.606g
O = 1.390g
Next, we divide the above by their molar masses
N = 0.606/14 = 0.0432
O = 1.390/16 = 0.0869
Next, we divide by the smallest
N = 0.0432/0.0432 = 1
O = 0.0869/0.0432 = 2
The empirical formula is NO2
The molecular formula is given by:
[NO2]n = 92
[14 + (16x2)]n = 92
[14 +32]n = 92
46n = 92
Divide both side by the coefficient of n i.e 46
n = 92/46
n = 2
The molecular formula = [NO2]n = [NO2]2 = N2O4
