Answer:
1•323
Explanation:
mass of carbon=12
mass of oxygen=2*16=32
no of moles = 3/44
PV=nRT
V=(0.06818*8.31*288)/123.3*10^3

i think the answer is cooling a liquid
C can be the only correct answer - 6.023 x 10^23 is the amount of molecules in a mol of an element. 4.5 x 6.023 x 10^23 can not equal anything but C.
4.5 x 6.023 x 10^23 = 2.71035 x 10^24
When the salt dissolves, it dissociates as follows;
AB --> A⁺ + B⁻
The molar solubility is amount of moles of the salt that can be dissolved in 1 L of solution.
solubility of the salt is - 2.60 g/L, to find molar solubility we have to multiply by the molar mass.
2.60 g/L /241 g/mol = 0.0108 mol/L
ksp = [A⁺][B⁻]
molar solubility of salt is equal to the molar solubility of cation and anion
ksp = (0.0108)(0.0108)
ksp = 1.17 x 10⁻⁴
