What is the mass of 4.00 moles of NaCl?
The molar mass of sodium chloride is 58.4 g/mol. This means that one mole of NaCl will weigh 58.4. 4 moles of NaCl will weigh 4 times as much. We can…
What is the mass of 2 mole of NaCl?
Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g. One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g. Concept 2.
What is the mass of 2.5 moles of NaCl?
Answer: molar mass of NaCl is 58.5 gm/mol.
How many formula units are in 3 moles of sodium chloride?
Looking at sodium chloride, NaCl, for every mole of NaCl there are Avogadro’s number of formula units (molecules). So the number of formula units of NaCl (molecules) in 3.2 moles = 3.2 moles x 6.02×1023 form. units/mole = 1.93×1024 formula units (molecules).
How many atoms are in 3.5 moles sodium?
of atoms = 3 × 6.022 × 10^23 = 18.066 × 10^23 atoms.
