Answer:

6.50 grams of the compound X is nitrogen

Explanation:

Step 1: Data given

Mass of compound X = 37.8 grams

Compound contains 17.2 % N

Step 2: Calculate mass of nitrogen

Mass nitrogen = % Nitrogen * total mass

Mass nitrogen = 17.2 % * 37.8 grams = 0.172 * 37.8 grams

Mass nitrogen = 6.50 grams

6.50 grams of the compound X is nitrogen

kvv77 [185]

Answer:

The mass of the surrounding is M_t = 263.9 \ g

Explanation:

From the question we are told that

      The mass of  NaOH is  m = 13.9 \ g

      The mass of water is m_w = 250.0g

      The chemical equation for the dissociation process is

       NaOH _{(s) } ---> Na^{+}_{(aq)} + OH^{-} _{(aq)}

       The specific heat capacity of the mixture is c_p = 4.18 J g^{-1} C^{-1}

       

The combined mass of the solution is

         M_t = 13 + 250

         M_t = 263.9 \ g

The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is  

  M_t = 263.9 \ g
