Answer:
Step-by-step explanation:
- To determine the number of moles of NaHCO3 that are reacted, we need to know the mass of the NaHCO3 that is being reacted. Without that information, we cannot calculate the number of moles.
If you provide the mass of NaHCO3 that is being reacted, I would be happy to help you calculate the number of moles.
- To calculate the number of moles of NaHCO3, we need the mass of the substance that is being reacted. With the mass of NaHCO3 and its molar mass, we can determine the number of moles using the following formula:
Number of moles = Mass / Molar mass
Please provide the mass of NaHCO3 involved in the reaction, and I will assist you further in calculating the number of moles.
- The molar mass of NaHCO3 (sodium bicarbonate) can be calculated by adding up the atomic masses of its constituent elements.
The atomic masses are as follows:
Na (sodium) = 22.99 g/mol
H (hydrogen) = 1.01 g/mol
C (carbon) = 12.01 g/mol
O (oxygen) = 16.00 g/mol (there are three oxygen atoms in NaHCO3)
Now, let's calculate the molar mass of NaHCO3:
Molar mass of NaHCO3 = (1 × Na) + (1 × H) + (1 × C) + (3 × O)
= 22.99 g/mol + 1.01 g/mol + 12.01 g/mol + (3 × 16.00 g/mol)
= 22.99 g/mol + 1.01 g/mol + 12.01 g/mol + 48.00 g/mol
= 84.01 g/mol
Therefore, the molar mass of NaHCO3 is approximately 84.01 g/mol.
