A)
1 g/cm³ --------------- 0.001 kg/cm³
5.52 g/cm³------------ ?
5.52 x 0.001 / 1
= 0.00552 kg/cm³
b) 1 g/cm³ ----------- 62.428 lb/ft³
5.52 g/cm³ ------- ?
5.52 x 62.428 / 1
= 344.60 lb/ft³
hope this helps!
You did not provide the statement, however, the most accurate things about atoms is that everything is made out of them in the entire universe, and they consist of protons, electrons, and neutrons. They create all substances in existence.
Gold is a element. Hope this helps
We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.
Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J
Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).
