Answer:
You take the mass of carbon dioxide, 56.8g, divide by its molar mass, 44.01g/mol, to produce the moles of carbon dioxide. This is multiplied by the molar ratio of butane/CO2, (2/8) = 1/4, which gives the moles of butane required to produce the carbon dioxide.
Explanation:
go to google
Theres 3 on the left side and 2 on the right side. 5 in total :)
Molar mass NaOH = 39.997 g/mol
Number of moles :
n = mass of solute / molar mass
n = 11.5 / 39.997
n = 0.287 moles
Therefore :
Molarity = moles solute / volume
Molarity = 0.287 / 1.5 => 0.1913 M
Answer:
compound 1 = 0.749gF / 1.0gl
compound 2 = 0.4489gF / 1.0gl
compound 3 = 1.047gF / 1.0gl
Explanation:
Given that;
compound mass of iodine in grams mass of fluorine in grams
1 4.75 3.56
2 7.64 3.43
3 9.41 9.86
a) Calculate the mass of fluorine per gram of iodine in each compound:
- compound 1
mass of Fluorine = (3.56gF / 4.75gF) * 1.0gl
= 0.749gF
Now RATIO = 0.749gF / 1.0gl
- compound 2
mass of Fluorine = (3.43gF / 7.64gF) * 1.0gl
= 0.4489gF
Now RATIO = 0.4489gF / 1.0gl
- compound 3
mass of Fluorine = (9.86gF / 9.41gF) * 1.0gl
= 1.047gF
Now RATIO = 1.047gF / 1.0gl
