You calculate the amount of loads of laundry as follows:
((6 x 0.25)/ load) x 10 loads = 15.00 total cost required for laundry
<span>(6.00 / 60 min) x (75 min/shift) = 7.50 cost / shift </span>
15.00 / (7.50 / shift) = 2 loads of laundry
Hope this answers the question.
Answer:
53.4 % is the percent yield
Explanation:
This is the reaction:
C₆H₆ + Cl₂ → C₆H₅Cl + HCl
First of all we need to know the moles of benzene we used
39 g . 1 mol / 78 g = 0.5 moles
Ratio is 1:1 so 1 mol of benzene produces 1 mol of chloride
0.5 moles of chloride were produced by 0.5 moles of benzene
We must calculate the mass of chloride we produced
0.5 mol . 112.45 g / 1 mol = 56.2g
Let's calculate the percent yield
(Yield produced / Theoretical yield ) . 100
(30 g / 56.2 g) . 100 = 53.4 %
