Explanation:
from definition of density we have
density=mass/volume
and density=55 mass=220g
volume=220/55
volume=4ml
or 4×10^-3l
Answer:
the atom is neutral, the nucleus is positive
Explanation:
(P1)(V1)=(P2)(V2)
(2.52 atm)(125 L)=(1.50 atm)(x L)
(315)/(1.50)=(V2)
V2=210 L
Heat energy= mass x specific heat x change in temperature
change in temperature=47.0=10.0= 37 degrees
convert mass in G = 6.83x1000=6830g
Heat energy is hence= 6830 x 4.184 j/g/degrees x 37=1057338.64 j or 1057.33864Kj
