Step-by-step explanation:
Subtract 1,400 by 1,000 then divide by 1,000
Answer:
28
Step-by-step explanation:
28 = 7 x 4
So,
7 is a factor of 28.
6/8 *3/2.
6*3=18. /8*2=16
18/16
Divide top and bottom by 2
9/8
To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3. 2g of AlCl3 contains 9.034*10^21 molecules.
<h3>Number of Molecules in 2g of AlCl3</h3>
The molar mass of AlCl3 is given as 133.34g/mol
Data;
- mass = 2g
- molar mass = 133.34g/mol
Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

If we equate this

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.
