Answer:
98 moles of H₂O.
Step-by-step explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2HCl + CaCO₃ —> CaCl₂ + H₂O + CO₂
From the balanced equation above,
1 mole of CaCO₃ reacted to produce 1 mole of H₂O.
Finally, we shall determine the number of mole of H₂O produced by the reaction of 98 moles of CaCO₃. This can be obtained as follow:
From the balanced equation above,
1 mole of CaCO₃ reacted to produce 1 mole of H₂O.
Therefore, 98 moles of CaCO₃ will also react to produce 98 moles of H₂O.
Thus, 98 moles of H₂O were obtained from the reaction.
