How many moles are present in a sample of HCl with a mass of 3.65?
0.1mol
How many moles of NaHCO3 are present in a 6.10 g sample?
Divide 6.10 (g NaHCO3) by 84.007 (g.mol−1 NaHCO3) to get 0.0726 mol NaHCO3
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 NaCl would form from 3.25 moles of NaHCO3?
The same amount.
