Atorsion balance has a sensitivity requirement (sr) of 6.0 mg. what is the mwq of this balance if the maximum error permitted in using it is 4.2%? [round answer to a whole number]

MWQ is 143 mg

Step-by-step explanation:

given data

sensitivity requirement (SR) =  6.0 mg

maximum error = 4.2%

to find out

MWQ

solution

we know here MWQ formula that is

MWQ =     ................1

so here error is 4.2 % = 0.042

put here all these value in equation 1 we get

MWQ =

MWQ =

MWQ = 142.857 mg

so MWQ is 143 mg

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
