Final answer:
The number of grams of sodium present in a 4.29 x 10^1 g sample of NaHCO3 is 22.99 g.
Step-by-step explanation:
To determine the number of grams of sodium present in a 4.29 x 10^1 g sample of NaHCO3, we need to calculate the molar mass of NaHCO3 and then convert the mass to grams of sodium. NaHCO3 consists of one sodium atom, so its molar mass is equal to the atomic mass of sodium, which is 22.99 g/mol. To convert the mass to grams of sodium, we can use the following conversion factor: 1 mol NaHCO3 = 1 mol Na = 22.99 g Na. Therefore, the correct answer is option B) 22.99 g.
