Answer 1

Answer:

The IV will run $66.67 \ ml /hr$

Step-by-step explanation:

From the question we are told that

   The mass of Magnesium sulfate is  $m_g = 30 \ g$

   The volume of the Magnesium sulfate  $V_R = 500ml$

   The rate at which the dose of the solution (Magnesium sulfate + Lactated Ringers. ) is infused is  $R = 4g/hr$

   

The concentration of Magnesium sulfate in Lactated Ringers  is mathematically evaluated as

         $C_m = \frac{m_g}{V_R}$

substituting values

          $C_m = \frac{30}{500}$

          $C_m = 0.06\ g/ ml$

This implies that

     0.06 g of Magnesium sulfate is in every 1 ml of  Lactated Ringers

So  4 g  of  Magnesium sulfate is in x ml of  Lactated Ringers

So

        $x = \frac{4}{0.06}$

       $x = 66.67 \ ml$

So the amount of the solution in ml that is been infused in 1 hour is  

      $66.67 \ ml /hr$
