Answer:
21g
Explanation:
no.ofmol fe2o3=39.5/(56×2+16×3)=0.25mol
from equation 1mole fe2o3 react with 3mole co
so,0.25mol fe2o3 react with 0.75mol co
mass of co=0.75×(12+16)=21g
Answer:
The independent variable in on the x-axis, and the dependent variable is on the y-axis.
Explanation:
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).If you are confused, please check out this website talking more in-depth about graphing!

Answer:
133.33 g/mole
Explanation:
To get the molar mass, you will need to first determine the atoms in the compound.
AlCl₃
We have aluminum (Al) and Chlorine (Cl)
Next step is to determine how many atoms of each element you have in the compound. The subscript will tell you how many. If you see no subscript, that means 1 atom.
Al = 1 atom
Cl = 3 atoms
Then you multiply the number of atoms by the atomic weight to get the molar mass of each element and add them up to get the total molar mass of the compound:
Element # of atoms atomic weight molar mass
Al 1 x 26.98 g/mole = 26.98 g/mole
Cl 3 x 35.45 g/mole = <u>106.35 g/mole</u>
TOTAL = 133.33 g/mole
