Alloys are preferable at times because they offer interesting properties than pure metal. Alloys are made in order to modify or enhance properties, especially mechanical properties. Examples are stainless steel, brass and wrought iron.
Answer:
C47N9O18 is the empirical formula of this compound.
Explanation:
Answer:
CO.
Explanation:
Assuming the given percentages are by mass, we can solve this problem via imagining we have <em>100 g of the compound</em>, if that were the case we would have:
Now we <u>convert those masses into moles</u>, using the<em> elements' respective molar masses</em>:
- 42.9 g of C ÷ 12 g/mol = 3.57 mol C
- 57.1 g of O ÷ 16 g/mol = 3.58 mol O
As the number of C moles and O moles is roughly the same, the empirical formula for the compound is <em>CO</em>.
