Answer:
The empirical formula is same as the molecular formula = C6H10S2O
Explanation:
we start by dividing the percentage of each of the elements by their atomic mass
Carbon = 44.4/12 = 3.7
Hydrogen = 6.21/1 = 6.21
Sulphur = 39.5/32 = 1.234375
oxygen = 9.89/16 = 0.618125
That of oxygen is smallest so we divide all by that of oxygen
C = 3.7 / 0.618125 = 6
H = 6.21/ 0.618125 = 10
S = 1.234375/ 0.618125 = 2
Automatically, oxygen is 1
So the empirical formula is;
C6H10S2O
Let’s get its molecular formula. We multiply each of the subscript by the number;
(72 + 10 + 64 + 16)n= 162
162n = 162
n = 1
So the molecular formula is same as the empirical formula
Sulfur normally has 16 electrons (see the periodic table), but the 2- indicates that the atom is gaining 2 electrons. because of that, the answer would be 18.
hope this helped!
Answer:
The molar mass of MgCI2 is 95.211 g/mol
Answer:
Yes, there are forces of attraction between the surfaces.
It is adhesive force.
Explanation:
Adhesive force is the bonding between two or more molecules of different materials, causing them to stick together.
Prokaryote cells are single celled organisms
