The density of carbon tetrachloride, given the data is 1.59 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
with the above formula, we can determine the density of carbon tetrachloride. Details below:
<h3>How to determine the density of carbon tetrachloride</h3>
The following data were obtained from the question:
- Mass of flask = 345.8 g
- Mass of flask + carbon tetrachloride = 703.55 g
- Mass of carbon tetrachlorcide = 703.55 - 345.8 = 357.75 g
- Volume of carbon tetrachlorcide = 225 mL
- Density of carbon tetrachlorcide =?
Density = mass / volume
Density of carbon tetrachlorcide = 357.75 / 225
Density of carbon tetrachlorcide = 1.59 g/mL

Answer:
sorry can't read in spanish:/ can you please put it in english for me.
Hey there!:
Given % of Mn=59.1% means 59.1 g of Mn present in 100 g of manganese fluoride.
Molar mass of Mn= 54.938 g/mol
Moles of Mn = mass / molar mass
59.1 /54.938 => 1.07 ≈ 1 mol.
and % of F=40.9% means 40.9 g of of F present in 100 g of manganese fluoride.
Molar mass of F=18.998 g/mol
Moles of F :
40.9 / 18.999 => 2.15 mol ≈ 2 mol.
The mole ratio between Mn:F= 1 : 2
Therefore the empirical formula of manganese fluoride:
=> MnF2=Mn1F2
Hope that helps!
