1H is the most abundant.
1H has mass nuimber 1, 2H has mass number 2, 3H has mass number 3
It is evident that the only way of having a mean mass number of 1.008 amu, the isotope with mass number 1 amu has to be superabundant.
Answer:
I cant really explain what you cant use but you use cubic centimeters, cubic meters, or liters.
Explanation:
Remember the volume is how much space something takes up, and the only way to identify the volume is by using something you can convert into something else, like centimeters into cubic meters (100 cm³ is equal to 1 m³), and liters (same thing, but in liquid form.)

Answer:
27.38 g
Explanation:
- CH₃NO₂ (l) + 3O₂ (g) → 4CO₂ (g) + 6H₂O (l) + 2N₂ (g) ΔHorxn = -2836 kJ
The value of ΔHorxn tells us that when 1 mol of CH₃NO₂ is burned, 2836 kJ of heat are produced. With that in mind we can<u> calculate how many moles of CH₃NO₂ were burned when 1273 kJ of heat were produced</u>:
- 1273 kJ * 1mol / 2836 kJ = 0.4489 mol
Then we <u>convert 0.4489 moles of CH₃NO₂ to grams</u>, using its <em>molar mass</em>:
- 0.4489 mol * 61 g/mol = 27.38 g
