Answer:
The mass of material is 96.12 g
.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
density of material = 2.7 g/mL
volume= 35.6 mL
mass= ? (in g)
Now we will put the values in the formula,
d= m/v
m=d×v
m= 2.7 g/mL × 35.6 mL
m= 96.12 g
so, the mass of material is 96.12 g
.
This temperature in units of degree Celsius is..
-78° Celsius
Molecular wt if ethene = 28 g/mol
take 14 ÷ 28 = 0.5 mol
since there is a 1:1 ratio between ethene and ethanol one should produce 0.5 mol
MW ethanol = 46
0.5 × 46 = 23 g should be produced.
17.25/23 = 0.75 = 75% Percent yield
The answer to ur question Molecular motion
T is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden.
