It is a molecule of the compound.
Which mento will explode first?
<span>2 H</span>₂<span> + O</span>₂<span> = 2 H</span>₂<span>O
4 g H</span>₂ ------------ 32 g O₂----------- 36 g H₂O
<span> 8 g H</span>₂ ------------ 64 g O₂------------ ? g H₂O
<span>
Mass of H</span>₂O :
<span>
64 * 36 / 32 =
2304 / 32 = 72 g of H</span>₂O
<span>
hope this helps!

Average atomic mass of an element is a sum of the product of the isotope mass and its relative abundance.
For example: Chlorine has 2 isotopes with the following abundances
Cl(35): Atomic mass = 34.9688 amu; Abundance = 75.78%
Cl(37): Atomic mass = 36.9659 amu; Abundance = 24.22 %
Average atomic mass of Cl = 34.9688(0.7578) + 36.9659(0.2422) =
= 26.4993 + 8.9531 = 35.4524 amu
Thus, the term “ average atomic mass “ is a <u>weighted</u> average so it is calculated differently from a normal average
Answer:
D
Explanation:
Volume in math is the mass of liquid required to fill up a container.
It is not C, the space occupied by a liquid.
It is not B, the space occupied by mass.
It is not A, width x height, because width x height is area.
So, the answer is D.
Hope this helps!
