Hydrogen + oxygen --> water
59,1g + x = 528g
528g - 59,1 = x
x = 468,9g
Answer:
d. Mass is the measure of the earth’s gravitational attraction of a body
This is FALSE. Mass is the measure of matter than an object contains.
Explanation:
b. An atom is the smallest particle of an element that still contains properties of the original element.

Antibodies are produced by a type of white blood cell called a plasma cell.
<span>Mass of KCl= 88.4g
</span>Molar mass of KCl=39+35.5
<span> =74.5
</span><span> The Moles of KCl= 88.4/74.5
</span> =1.186
<span>If for the 2 moles of KCl there are 3 moles of oxygen
</span>so
<span>1 mole of KCl will give=3/2=1.5 moles of oxygen
</span>
<span>1.186 moles of KCl will give =1.5*1.186=1.779 oxygen
</span><span>32 the molar mass of oxygen
</span>so its mass will be
<span>1.779 *32=56.928
