14. Let g represent Gupta's age. You can solve the equation 2g - 5+ g = 31 to find g. Which property would not be used in solvin
1 answer:
Answer:
B. Commutative Property of Addition
Explanation:
To find out the property that would not be used in solving this equation, we solve for g.
We have applied the following:
A. Addition Property of Equality/D. Subtraction Property of Equality
C. Division Property of Equality
Therefore, the property that would not be used is:
B. Commutative Property of Addition

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.
