The formula for water is H2O so there would have to be two Hyrdogens and one oxygen. Therefore it would be 4g of Hydrogen and 16g of Oxygen leaving you with 20g.
The answer is D.
Hope this helps :) ~
It is a Non-metal, this is chemistry.
Answer:
density = 0.822 g/mL
Explanation:
We calculate the density knowing the flowing formula:
density = mass / volume
mass = 2.98 grams
volume = 21.1 × 14.2 × 12.1 = 3625 mm³ = 3.625 cm³ = 3.625 mL
density = 2.98 / 3.625 = 0.822 g/mL
Animals that rely on coral for protection and cover, such as grouper, snapper, oysters and clams, would also be negatively impacted. And because this marine life is a vital staple in many peoples' diets, the death of the coral reefs would exacerbate the problem of feeding these groups [source: Skoloff].
FeO·TiO₂
w(Ti)=M(Ti)/M(FeO·TiO₂)
w(Ti)=47.88g/mol/151.73g/mol=0.3156 (31.56%)
