How many moles of NaHCO3 are present in 3.00 g sample?

To find the moles of NaHCO3 in a 3.00 g sample, first calculate the molar mass of NaHCO3 (84.01 g/mol). Then, divide the mass of the sample by the molar mass to obtain the moles of NaHCO3. For this sample, 3.00 g / 84.01 g/mol ≈ 0.036 moles of NaHCO3 are present.


How many lb-moles of substance are present in the given sample?

To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.


How many moles of a substance are present in a sample if the sample weighs 5 grams and the molar mass of the substance is 30 g/mol (Dalton to moles conversion)?

To find the number of moles in a sample, divide the sample's weight by the molar mass of the substance. In this case, if the sample weighs 5 grams and the molar mass is 30 g/mol, the number of moles present in the sample would be 0.167 moles.


How many moles of NaCl would form from 3.25 moles of NaHCO3?

To find the moles of NaCl formed from NaHCO3, we need to consider the stoichiometry of the reaction. The balanced equation is: 2 NaHCO3 -> Na2CO3 + H2O + CO2 Therefore, for every 2 moles of NaHCO3, we get 1 mole of NaCl. Therefore, 3.25 moles of NaHCO3 would produce 1.625 moles of NaCl.


How many moles of magnesium are in a sample of 56.4 of magnesium?

To determine how many moles of magnesium are in a sample of 56.4 g, you would first calculate the molar mass of magnesium (about 24.3 g/mol). Then, divide the mass of the sample by the molar mass to obtain the number of moles present (around 2.32 moles in this case).


How many moles are in 2.10 kg of NaHCO3?

For this you need the atomic (molecular) mass of NaHCO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaHCO3=84.0 grams110 grams NaHCO3 / (84.0 grams) = 1.31 moles NaHCO3


How many moles of a substance with an atomic mass unit (amu) of 12 are present in a given sample?

To find the number of moles in a sample, divide the sample's mass by the substance's atomic mass unit (amu). For a substance with an amu of 12, the number of moles in the sample can be calculated by dividing the sample's mass by 12.
