Answer» Correct Answer - B Use the formula: `(t_(10%("left")))/(t_(1//2)) = log((100)/(10))/(0.3)` `t_(10%)("left") = (t_(1//2) xx 1)/(0.3)` `= (10 min)/(0.3) = 33 min`.Correct Answer - B Use the formula: `(t_(10%("left")))/(t_(1//2)) = log((100)/(10))/(0.3)` `t_(10%)("left") = (t_(1//2) xx 1)/(0.3)` `= (10 min)/(0.3) = 33 min`. |
