Answer to Question #318199 in General Chemistry for Musonda Elvis

Question

A 0.205 g sample of CaCO3 (Mr = 100.1 g/mol) is added to a flask along with 7.50 mL of 2.00 M HCl.

CaCO3(aq) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)

Enough water is then added to make a 125.0 mL solution. A 10.00 mL aliquot of this solution is taken and titrated with 0.058 M NaOH.

NaOH(aq) + HCl(aq) → H2O(l) + NaCl(aq)

How many mL of NaOH are used?

Answer 1

188ml
