Well countries near the quitter of warmer than countries than the poles. So the mystery island would probably be near the equator near Florida or in Florida

Using the volumes of sodium thiosulfate solution you just entered, the mass of bleach sample, and the average molarity of the so
dedylja [7]

Answer:

3.18 (w/w) %

Explanation:

In the problem, you can find mass of NaClO knowing the reaction of NaClO with Na₂S₂O₃ is:

NaClO + 2Na₂S₂O₃ + H₂O → NaCl + Na₂S₄O₆ +2NaOH + NaCl

<em>Where 1 mole of NaClO reacts with 2 moles of Na₂S₂O₃</em>

<em> </em>Moles of thiosulfate in the titration are:

0.0101L ₓ (0.042mol / L) = 4.242x10⁻⁴ moles of Na₂S₂O₃

Thus, moles of NaClO in the initial solution are:

4.242x10⁻⁴ moles of Na₂S₂O₃ ₓ (1mol NaClO / 2 mol Na₂S₂O₃) = 2.121x10⁻⁴ moles NaClO

As molar mass of NaClO is 74.44g/mol, mass of 2.121x10⁻⁴ moles are:

2.121x10⁻⁴ moles ₓ (74.44g / mol) = <em>0.0158g of NaClO</em>

As mass of bleach is 0.496g, mass percent is:

0.0158g NaClO / 0.496g bleach ₓ 100 =

A physician ordered 5.0 mg of methylprednisolone. Calculate the ccs required if methylprednisolone is available as 10 mg/2 cc.
notsponge [240]

The ccs required if methylprednisolone is available as 10 mg/2 cc is 11642.4 mcg

  • Here for 100 units of heparin 1 ml is required. Now for forty units of heparin (1/100)*40ml = 0.4ml of heparin is required.
  • For 10mg of methylprednisolone, 2mL is required. So for 5.0mg of methylprednisolone, (2/10)×5.0 mL = 1 mL is required.
  • For 125mg(0.125g) vancomycin, 1mL is required.So for 0.25g vancomycin, (1/0.125)×0.25mL = 2mL is required.
  • For 1kilogram per minute, the doctor ordered 2mcg of propofol.
  • For 10kilogram per minute, the doctor ordered 20mcg of propofol.
  • Now, for 44lb(= 44×2.205kg) per minute the doctor has to order 44×2.205×2 mcg = 194.04mcg of propofol .
  • So now per hour, the 44lb patient requires 194.04×60mcg = 11642.4 mcg of propofol.
