How many millilitres of 0 .5 M H 2 SO 4 are needed to dissolve 0 .5 g of copper(II)carbonate? Report your answer by rounding it up to nearest integer.

Correct answer

Step-by-step solution

The balanced chemical reaction is: CuCO 3 + H 2 SO 4 → CuS0 4 + H 2 O + CO 2 milli mol of CuCO 3 = 0.5 × 1000 123.5 = 4.048 mM milli mol of H 2 SO 4 required = 4.048 mM = Molarity x Volume (in mL) Volume = 4.048 0.50 = 8.1 mL
