To test the stoichiometry of a reaction, a student placed a copper wire into a solution of silver nitrate. The reaction is Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s) The student collected and recorded the following data: Mass of Cu(s) before reaction = 25.80 g Volume of AgNO3(aq) = 200 mL Concentration of AgNO3(aq) = 0.350 mol/L What mass (in g) of copper metal remains unreacted after the reaction has finished? Express your answer with three significant digits. Do not include units! g Cu

g Al(s) To test the stoichiometry of a reaction, a student placed a copper wire into a solution of silver nitrate. The reaction is Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s) The student collected and recorded the following data: Mass of Cu(s) before reaction = 25.80 g Volume of AgNO3(aq) = 200 mL Concentration of AgNO3(aq) = 0.350 mol/L What mass (in g) of copper metal remains unreacted after the reaction has finished? Express your answer with three significant digits. Do not include units! g Cu A 1.00 L sample of cooking gas taken from a cylinder was collected. Its mass, measured at 27.0° C and 100 kPa, was 1.768 g. Calculate the molar mass of the cooking gas in g/mol. Proctorio is sharing your screen. Stop sh
