Question

In a coffee cup calorimeter, what volume of 1.0 M NaOH was used?

a) 100.0 ml
b) 50.0 ml
c) 200.0 ml
d) 75.0 ml

Answer 1

The correct volume of 1.0 M NaOH used in the coffee cup calorimeter, as referenced in the examples, is 50.0 mL.

Step-by-step explanation:

To determine the volume of 1.0 M NaOH used in the coffee cup calorimeter, we can refer to the provided examples regarding heat produced by an exothermic reaction. In the examples given, the volume of NaOH is consistently represented as 50.0 mL when it is mixed with an equal amount of HCl to produce a temperature increase in the calorimeter. The reaction of HCl and NaOH in such a setup is typical of a neutralization reaction, where equimolar amounts of acid and base react to form water and a salt. Based on these examples, the correct volume of 1.0 M NaOH used in the coffee cup calorimeter is 50.0 mL (b).
