Answer:
job A
Step-by-step explanation:
job B pays $34560 yearly because every since it pays $720 weekly and there are 48 weeks in a year $720 multiplied by 48 is $34560. Job C pays $37440 because there are 12 months in a year and semimonthly means two times per month so 12 times 2 times $1560 give you $37440. Therefore job A pays the most amount per year.
Answer: 248mL
Step-by-step explanation:
Given:
Concentration of buffer solution Cs = 1.24%w/v of boric acid
Concentration of boric acid solution Cb = 5 % w/v boric acid
For 1 liter of buffer solution, the weight of boric acid needed is:
mb = 1 × 1.24 = 1.24 unit weight
mb = Cb × Vb .....1
Cb = concentration of boric acid solution.
Vb = volume of boric acid solution needed.
mb = weight of boric acid needed.
From equation 1.
Vb = mb/Cb
Vb = 1.24/5
Vb = 0.248L
Vb = 248mL
