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
Answer:
1000 meters
Measure of Lengths
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm) = 100 millimeters
100 centimeter = 1 meter (m) = 1,000 millimeters
1000 meters = 1 kilometer (km)
Explanation:
Hope this helps :)
0.5 mg/mL would be expressed as 500 ug/uL
Liquid will no pour out. At the bottom the separating funnel consists of a valve it allow the liquid to flow out.The lid is on the top to pour in liquid from the top,it is air tight. Therefore as long as the lid is put, the liquid will not flow out at the bottom. The reason is that ,the incoming air has no way to get into the flask.
