Explanation:
Hi for this one u just need to remember and use the equation.

then u find mr of potassium which is 39.1.
then u do

you get the answer as 0.5115 write ur answer to 3 significant figures which will be 0.512 moles .
hope this helps :)

<u>Explanation:</u>
- A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer.
- Radio-tracking technology assists in determining exactly where an animal is located at any instant in time and frequently what that animal is performing! Utilizing the data collected from tracking devices, scientists can conclude the day-to-day activities of an animal, the size of an animal's place range, what other animals share an animal's range and the types of habitats an animal practices.
- Gamma-rays are the common energetic form of light and are generated by the most heated regions of the universe. Gamma rays are provided by such extreme events as supernova explosions or the elimination of atoms and by less exciting events, such as the breakdown of radioactive material in space.
The balanced equation for the above reaction is;
CH₄ + 2O₂ ---> CO₂ + 2H₂O
Stoichiometry of CH₄ to O₂ is 1:2
The number of methane moles present - 1.44 g/ 16 g/mol = 0.090 mol
Number of oxygen moles present - 9.5 g/ 32 g/mol = 0.30 mol
If methane is the limiting reagent,
0.090 moles of methane react with 0.090x 2 = 0.180 mol
only 0.180 mol of O₂ is required but 0.30 mol of O₂ has been provided therefore O₂ is in excess and CH₄ is the limiting reactant.
Number of moles of water that can be produced - 0.180 mol
Therefore mass of water produced - 0.180 x 18 g/mol = 3.24 g
Therefore mass of 3.24 g of water can be produced
