Answer:
The mass ratio of oxygen rounded to the nearest whole no. 3 : 2
Explanation:
According to Law of Multiple proportion when two elements combine to make two or more different compounds, the mass ratio of the two element in the first compound, when divided by the mass ratio of the second compound , form a simple whole number ratio.
Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen
Compound B contains 11.63 g of sulfur for every 10.49 g of oxygen
Ratio of oxygen in each compound
always put the larger number over the smaller number.

There are 1.66 1 molecules in 1 gram of nicotine.
<u>Explanation</u>:
Nicotine is an organic compound with the chemical formula of
Given the mass of nicotine = 4.50 g
Molecular mass of Nicotine = 162.23 g/mol
Moles of a compound = given mass / molar mass of the compound
=
The Number of molecules of compound:
Moles Avogadro number = 0.0277 6.023 1
= 1.66 1 molecules.
There are 1.66 1 molecules in 1 gram of nicotine.
8 minutes and 25 seconds is the same as 8.25 in decimal form.
Divide by 60 minutes.
60 / 8.25 = 7.27 miles per hour
Best of Luck!
