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.

Greg's daughter will have $533 in her piggy bank in a year
The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.
Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday
- Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
- Amount deposited on Sunday = $5.75
- Total amount = $5.75 + $4.50 = $10.25
The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week
Total amount in a year = number of weeks in year x the total amount saved in a week
- Number of weeks in year = 52
- The total amount saved in a week = $10.25
$10.25 x 52 = $533
In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year
