When the object has something added to it
<span>Water soaks into it easily and during freeze-thaw cycles would be more likely to break apart because of the water freezing and thawing inside the rock. The water freezes and expands inside the rock, causing the surface to break off in flakes from the pressure of the expanding ice inside.</span>
Assuming that the 18.8% composition is based on mass,
therefore the mass of Lithium would simply be the product of the fractional
composition and the total dose. That is:
18.8 % = 0.188
mass Lithium = 0.188 * 1.00 g = 0.188 g
Answer:
<span>0.188 g</span>
