It has a fixed mass
it does not change with the shape of the container
it cannot be compressed
it has fixed atom and molecules and limited to very small displacement
only vibrational motion occur in the molecules of solid .
Polar protic solvents actually speed up the rate of the unimolecular substitution reaction because the large dipole moment of the solvent helps to stabilize the transition state. The highly positive and highly negative parts interact with the substrate to lower the energy of the transition state.
Answer:
0.0250 g
Explanation:
Step 1: Determine the molar mass of Vitamin C.
The molar mass is the mass in grams corresponding to 1 mole. In order to calculate the molar mass of vitamin C (C₆H₈O₆) we need to add the molar masses of the elements that compose it.
M(C₆H₈O₆) = 6 × M(C) + 8 × M(H) + 6 × M(O)
M(C₆H₈O₆) = 6 × 12.01 g/mol + 8 × 1.01 g/mol + 6 × 16.00 g/mol
M(C₆H₈O₆) = 176.14 g/mol
Step 2: Calculate the mass corresponding to 0.000142 mol of vitamin C.
