$\huge\underline\bold{Question:}$

Calculate the mass of :
a) 0.5 mole of silver Ag-108
b) 0.5 mole of sugar (C12H22O11) ​

Answer 1

Answer:

= 12 × 12 + 22 × 1 u + 11 × 16 u = 342 u or 342 g/mol Now, to calculate mass, apply the formula: We can write: Mass(m) = Number of moles (n) × Molar mass of C12H22O11 (M) Mass = 0.5 mol × 342g/mol Mass = 171g Thus, the mass of 0.5 mole of sugar (C12H22O11) is 171g.
