It might be more suitable because some data cannot use a graph to show data because there is too much data.
Answer: Moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, 
.
Explanation:
Given: Mass of methane = 146.6 g
As moles is the mass of a substance divided by its molar mass. So, moles of methane (molar mass = 16.04 g/mol) are calculated as follows.
The given reaction equation is as follows.
This shows that 2 moles of hydrogen gives 1 mole of methane. Hence, moles of hydrogen required to form 9.14 moles of methane is as follows.
Thus, we can conclude that moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, .
4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.
<h3>What is the moles of Salt required to change the temperature of water by 5°C?</h3>
Based on the given equation, the molality of the solution is calculated as follows:
- Molality = change in temperature/ Kb × I
Change in temperature = 5 °C
Kb = 0.51
i = 2
Molality = 5/0.51 × 2 = 4.9 molal
Also, Molality = moles/kg of water
Moles of salt = molality × kg of water
Moles of salt = 4.9 × 1 = 4.9 moles.
Therefore, 4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.
