Answer:
b = 3w; 54
Step-by-step explanation:
Since the student reads 3 books in one week, we know that one book is three times the amount of weeks, or b = 3w
We can plug in 18 for w to find how many books are read in 18 weeks
b = 3w
b = 3(18)
b = 54
So after 18 weeks she has read 54 books
Answer:
513 g of C₁₂H₂₂O₁₁ will contain 18 moles of Carbon atoms.
Step-by-step explanation:
English Translation
You would know how to say the number of moles of carbon atoms in 513 g of C₁₂H₂₂O₁₁ (Molar mass of C₁₂H₂₂O₁₁: 342 g.
Solution
From the molecular formula for the compound,
1 mole of C₁₂H₂₂O₁₁ consists of 12 moles of carbon atoms.
We just need to find the number of molesnof the mass of C₁₂H₂₂O₁₁ provided.
Number of moles = (mass)/(molar mass)
Mass of C₁₂H₂₂O₁₁ = 513 g
Molar mass of C₁₂H₂₂O₁₁ = 342 g
Number of moles of C₁₂H₂₂O₁₁ present
= (513/342) = 1.5 moles
1 mole of C₁₂H₂₂O₁₁ consists of 12 moles of carbon atoms.
1.5 moles of C₁₂H₂₂O₁₁ will contain (1.5×12/1) moles of carbon atoms, that is, 18 moles of Carbon atoms.
Hope this Helps!!!
