10 cm in a cube to find volume is 10 by 10 by 10
1000 cm cubed
10 cm is 0.1 m
0.1 times 0.1 times 0.1 is 0.001 metres cubed
19,300 times 0.001 is
19.3 kg
approximately 193newtons
yes it could be passed around casually
Moles Ag = 68.3 g / 107.868 g/mol=0.633
Through hypothesis and experiments
Answer:

Explanation:
Given that,
Mass of sample, m = 996.9 g
The change in temperature of the sample, 
Heat produced, Q = 62.9 calories = 263173.6 J
The heat released by a sample due to change in temperature is given by :

Where
c is the specific heat capacity
So,

So, the specific heat of ethanol is equal to
.
