It represents the boundary between what is considered to be ionic or a covalent bond.
Answer:
43.2 g of table salt occupies 20.0 cm2of space- Appropriate for calculating density
150 g of iron density of iron 79.0 g/cm3- Appropriate for calculating volume
21.0 mL of methanol density of methanol 0.79g/mL - Appropriate for calculating mass
3.00 g of white pine, density of white pine 0.40 g/cm3- Appropriate for calculating volume
5.00 cm,3 of table salt weighs 10.8g-Appropriate for calculating density
Explanation:
Density is defined as mass per unit volume. Hence in science;
Density= mass/volume
When mass and volume are both given, the information can be used to determine the density of a given substance.
When volume and density are both given, the information can be used to determine the mass of a given substance.
When the mass and density of a substance are both given, the information can be used to determine the volume of the substance.
Hence the answers given above.
The molecular mass of 
is: 1·1 + 1·14.01 + 2·16 = 47.01 g/mol.
Now we can convert the mass into mol of :
Answer:
Explanation:
so we have to solve it or just answer it?
Answer:
major enantiomer = 90.5 %
minor enantiomer = 9.5 %
Explanation:
Assuming that the major isomer is in excess;
From, ee/2 + 50
ee = enantiomeric excess = 81%
% major
=81/2 + 50 = 90.5 %
% minor
= 100% - 90.5 %
% minor
= 9.5 %
