Answer: 0.4533mol/L
Explanation:
Molar Mass of CaCO3 = 40+12+(16x3) = 40+12+48 = 100g/mol
68g of CaCO3 dissolves in 1.5L of solution.
Xg of CaCO3 will dissolve in 1L i.e
Xg of CaCO3 = 68/1.5 = 45.33g/L
Molarity = Mass conc.(g/L) / molar Mass
Molarity = 45.33/100 = 0.4533mol/L
Answer:
umm i believe that the one you chose is correct
Explanation:
Q=44.0 ct
p=3.51 g/cm³
Δq=0.200 g/ct
m=q×Δq
v=m/p=q×Δq/p
v=44.0×0.200/3.51≈2.5 cm³
C. 2.5 cm³
Answer: Heat energy is absorbed to vaporize a liquid because molecules which are held together by intermolecular forces in the liquid are separated as the gas is formed
Explanation:whatever that means^ I looked it up
