we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
5.2/ 24.3 = 0.214
0.214 x 2 = 0.428
0.428 x 36.5= 15.6g
Answer:
Hey there!
Density=Mass/Volume
Density=54/20
Density=2.7 g/cm^3
Let me know if this helps :)
Answer:
0.4
The efficiency is defined as the work done divided by the heat provided at Th. ε = W/Qh = 400 J/1000 J = 0.4 The Carnot efficiency is given in terms of the high and low temperatures.
Hope this helps, please let me know if it is wrong.
