V(H₂O)=500 mL
p(H₂O)=0.9982 g/mL
m(H₂O)=V(H₂O)p(H₂O)
mass of salt solution:
m=m(H₂O)+m(CuSO₄)=V(H₂O)p(H₂O)+m(CuSO₄)
w = m(CuSO₄)/m
w=m(CuSO₄)/{V(H₂O)p(H₂O)+m(CuSO₄)}
w=2.5/{500*0.9982+2.5}=0.004984 (0.4984%)
Under the same conditions of temperature and pressure, a liquid differs from a gas because the particles of the liquid a) are in constant straight-line
Answer: the volume increases
Explanation: It increasses because the volume is how tall it is
Answer:
Explanation:
The formula of nickeI(II)nitrate hexahydrate is
Ni(NO3)2.6H2O
So option (c) is correct.
