Percent composition is mass of element over mass of compound times 100. 6.41 + 9.60 = 16.01 g of compound, so % composition of sulfur is 6.41/16.01 x100 or 40.0%. % oxygen is 9.60/16.01 x 100 or 60.0%.
119.37 g/mol
<h3>Further explanation</h3>
Relative atomic mass (Ar) and relative molecular mass / molar mass (M)
the molar mass/molecular mass of a compound : the sum of the relative atomic mass (Ar) of the constituent atoms
M AxBy = (x.Ar A + y. Ar B)
Atomic weight (Ar) of :
- C : 12.0107 g/mol
- H : 1.00784 g/mol
- Cl : 35.453 g/mol
The molar mass of CHCl₃

1. The metamorphic rocks are produced when the parent or the pre-existing rocks (whether sedimentary, igneous, or even metamorphic) are changed by pressure, heat, and the chemical activity of the fluids.
When the prime changing factor is heat, generally due to direct contact, it may go through fundamental modification in recrystallization and texture is known as contact metamorphism. While regional metamorphism takes place when the minerals and texture of the rock are modified by pressure and heat.
Answer:
FILTRATION.
filter the solution and separate sand and salt solution
evaporation
evaporate the water and salt mixture and salt will be left as a solid
So they can predict what happens next
