The answer is C
Because radical 38 would equal approximately 6.1644, which is what the line shows.
The first one cuz if u put it and draw it on a number line and make sense out of it you will see the first one makes sense
For 10% it will be 60, for 1% it's 6, 5% it's 30, 30% is 180, And 36% it will be 206
Hey there!
We know that ,
Circumference is a circle = 2 pi r
=> 2 pi r = 50.24
=> r = 50.24/2 x 3.14
=> r = 78.8 m
But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158
Option d is correct
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!!!
