5 0

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

If a child accidentally swallowed 1.6 fluidounces of FEOSOL Elixir, containing 2/3 gr of ferrous sulfate per 5 mL, how many mill
GuDViN [60]

Answer:

the amount of ferrous sulphate child will digest = 213.3 mg

Step-by-step explanation:

Given,

Amount of FEOSOL Elixir swallowed by child = 1.6 Fluid ounces

                                                                           = 1.6 x 29.57 ml

                                                                           = 47.312 ml

\textrm{Amount of ferrous sulphate contained in 5 ml of of solution}=\ \dfrac{2}{3}\ grams

\textrm{So, amount of ferrous sulphate contained in 1 ml of solution}\ =\ \dfrac{2}{3\times 5}

                                                                    =\ \dfrac{2}{15}

\textrm{So,the amount of ferrous sulphate contained in the 1.6 ml of FEROSOL}=1.6\times \dfrac{2}{15}

                  =\ \dfrac{3.2}{15}

                  = 0.2133 gram

                  = 213.3 mg

So, the amount of ferrous sulphate child will digest = 213.3 mg
