Answer:Cm=o,4 (Mol/l)
Explanation:
Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + H2O(l)
0,01 0,02
CM=n/V
Minimum number of boxes order is 52.4 boxes.
<u>Given that;</u>
Average use of pencil per student = 9.3 pencil per year
Number of student in school = 812 students
<u>Find:</u>
Minimum number of boxes order
<u />
<u>Computation:</u>
Total number of pencil used in year = 812 × 9.3
Total number of pencil used in year = 7,551.6 pencils
12 <u>dozen</u> = 1 <u>gross</u>
So,
Number of pencils in 1 box = 12 × 12
Number of pencils in 1 box = 144 pencils
Minimum number of boxes order = 7551.6 / 144
Minimum number of boxes order = 52.4 boxes
