QUESTION

The reaction of HNO3 with X2CO3 produces CO2, water, and XNO3

The reaction of HNO3 with X2CO3 produces CO2, water, and XNO3.

a. Write a balanced molecular reaction for this process.

b. If 17.4 mL of 0.10 M HNO3 was required to "neutralize" a 0.12 g sample of X2CO3, how many moles of HNO3 is this?

c. Based on your balanced equation, how many moles of X2CO3 must have reacted with the moles of HNO3 in (b)?

d. Use the sample mass and moles in (c) to calculate an approximate molar mass for X2CO3.
