$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
Answer:
D. 7 units.
Step-by-step explanation:
The length is not altered by the 2 translations.
It is √[ (-1-6)^2 + (2-2)^2]
= 7 units.
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.
