Answer:
The empirical formula is SF6 (option E)
Explanation:
Step 1: Data given
Mass of sulfur = 3.21 grams
Mass of fluorine = 11.4 grams
Molar mass sulfur = 32.065 g/mol
Molar mass fluorine = 19.00 g/mol
Step 2: Calculate moles
Moles = mass /molar mass
Moles sulfur = 3.21 grams / 32.065 g/mol
Moles sulfur = 0.100 moles
Moles fluorine = 11.4 grams / 19.00 g/mol
Moles fluorine = 0.600 moles
Step 3: Calculate mol ratio
We divide by the smallest amount of moles
S: 0.100 / 0.100 = 1
F : 0.600 / 0.100 = 6
The empirical formula is SF6 (option E)
Answer:
=> 2.8554 g/mL
Explanation:
To determine the formula to use in solving such a problem, you have to consider what you have been given.
We have;
mass (m) = 16.59 g
Volume (v) = 5.81 mL
From our question, we are to determine the density (rho) of the rock.
The formula:
![p = \frac{m}{v}](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7Bm%7D%7Bv%7D)
Substitute the values into the formula:
![p = \frac{16.59 g}{5.81 mL} \\ = 2.8554 g/mL](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B16.59%20g%7D%7B5.81%20mL%7D%20%5C%5C%20%20%20%3D%202.8554%20g%2FmL)
= 2.8554 g/mL
Therefore, the density (rho) of the rock is 2.8554 g/mL.
Answer: If you smell a dusty or burning smell the first few times you turn on your heat, it’s most likely dust and dirt that’s settled on components inside your heating system throughout the summer. As you fire up the heat, those dust particles burn away, producing a weird burnt/dusty smell.
