Molar mass Cu(OH)2 => 97.561 g/mol
Therefore:
1 mole Cu(OH)2 ------------ 97.561 g
? moles Cu(OH)2 ----------- 68 g
= 68 x 1 / 97.561
= 68 / 97.561
= 0.696 moles of Cu(OH)2

Answer:
0.00353J/g/°C
Explanation:
I will assume the temperature of the ice to be approximately 0°C.
Moreover, Heat of fusion of water is 6kJ
Amount of heat used to melt 5.3g of ice = 5.3 x 6 / 18
=1.767g°C
Therefore
1.767 = 25 x specific heat cap. x 200
Specific heat cap. = 1.767/(25x200)
= 0.00353J/g/°C
there's no picture here but I guess the answer would be:
considering the constant temperature, if you double the volume, the pressure would be halved.
like: volume is 2, pressure is 4
if 2×2, then:4÷2
