Answer:
![m_{O_2}=87.2gO_2](https://tex.z-dn.net/?f=m_%7BO_2%7D%3D87.2gO_2)
Explanation:
Hello.
In this case, given the chemical reaction, we can compute the grams of oxygen by using the 98.2 g of water via the 2:1 mole ratio between them, the molar mass of water that is 18.02 g/mol, the molar mass of gaseous oxygen that is 32.00 g/mol and the following stoichiometric procedure relating the given information:
![m_{O_2}=98.2gH_2O*\frac{1molH_2O}{18.02gH_2O}*\frac{1molO_2}{2molH_2O}*\frac{32.00gO_2}{1molO_2} \\\\m_{O_2}=87.2gO_2](https://tex.z-dn.net/?f=m_%7BO_2%7D%3D98.2gH_2O%2A%5Cfrac%7B1molH_2O%7D%7B18.02gH_2O%7D%2A%5Cfrac%7B1molO_2%7D%7B2molH_2O%7D%2A%5Cfrac%7B32.00gO_2%7D%7B1molO_2%7D%20%20%20%5C%5C%5C%5Cm_%7BO_2%7D%3D87.2gO_2)
In which the result is displayed with three significant figures because the given mass of water 98.2 g, has three significant figures too.
Best regards!
Answer:
other the effect of temperature on plants
Oxygen gas enters water through Diffusion (movement of gas from higher concentration to lower concentration). The amount of oxygen in water depends on many factors. Like at Higher temperature there will be less amount of Oxygen in water and vice versa. And it is found that at 0 °C, 14.6 mg/L and at 20 °C, 7.6 mg/L dissolves.
The interactions between Water Molecule and Oxygen Molecule are London Dispersion Forces. The polar water molecule induces the polarity in oxygen molecule. In this way the oxygen gas is available in water.
Helium has 8, calcium has 2, potassium has 1, carbon has 4 and argon has 8. Hope this helps. Please name this the brainiest thanks.
