Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. It is a property that can be used to describe a substance<span>.</span><span> It has standard units of kg/m^3 or g/cm^3.</span>
Answer:
C6H10Cl2
Explanation:
Convert mass % to mass
100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H
Molar mass
Cl = 35.5 g/mol
C = 12 g/mol
H = 1 g/mol
Find the number of moles:
Chlorine: 46.4g /35.5g/mol = 1,3 moles
Carbon: 47,05g/12 g/mol = 3,92 moles
hydrogen: 6,63g/1g/mol = 6,63 moles
Molar fraction:
Cl = 1,30/ 1,30 = 1
C = 3,92/ 1,30 = 3,01
H = 6,63/ 1.30 = 5,01
C3H5Cl = 76,5 g/ mol x 2 = 153 g/ mol
So multiply the molecular formula by two = C6H10Cl2
Answer:
c) disaccharides have more chemical bonds
Explanation:
disaccharides are made from the condensation of two monosaccharides.
This means there are more bonds in disaccharides. More bonds mean greater energy and vice versa .
The answer is B. Thermal Conductivity
