For this you need the atomic (molecular) mass of NaCN. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. NaCN= 49.0 grams
2.55 grams NaCN / (49.0 grams) = .0520 moles NaCN

How many MOLES of sodium nitrate are present in 2.85 grams of this compound?
To find the number of moles, first calculate the molar mass of sodium nitrate (NaNO3), which is 85 grams/mol. Then, divide the given mass (2.85 grams) by the molar mass to obtain the number of moles present, which is approximately 0.0335 moles.
If 2 moles of sodium carbonate are used in the reaction how many grams of sodium chloride will be formed?
By stoichiometry, 2 moles of sodium carbonate will produce 2 moles of sodium chloride. The molar mass of sodium chloride is approximately 58.44 g/mol, so 2 moles would weigh about 116.88 grams.
How many grams are in 4.5 moles of sodium?
To convert moles to grams, you need to use the molar mass of sodium. The molar mass of sodium is about 23 grams per mole. Therefore, 4.5 moles of sodium would be approximately 103.5 grams (4.5 moles * 23 grams/mole).
How many moles are in 454 grams in sodium?
To calculate the number of moles in 454 grams of sodium, you need to divide the given mass by the molar mass of sodium. The molar mass of sodium is approximately 23 grams/mol. Therefore, 454 grams of sodium is equal to 454/23 = 19.74 moles of sodium.
How many moles of sodium are in 120 grams?
To find the number of moles in 120 grams of sodium, divide the given mass by the molar mass of sodium. The molar mass of sodium is approximately 23 grams per mole. Therefore, 120 grams of sodium is equal to 120/23 ≈ 5.22 moles of sodium.
