NaCl (10.0 mol), 585 g.
How many moles are in NaCl?
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.
How many moles of sodium chloride NaCl does 58 grams represent?
Molar mass of NaCl
= (22.99+35.45)⋅g⋅mol−1. From where do you get these atomic masses? A tad under one mole.
How many moles of sodium chloride are present in 117 grams of sodium chloride?
1 mole of NaCl has 2 moles of ions, 1 mole of Na+ and 1 mole of Cl-. 3. Number of moles of ions = 2(2) = 4 moles of ions.
What is the formula for moles?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
How many moles of NaCl are in 100 grams of NaCl?
Answer Expert Verified
If you check the Periodic table, to Molar Mass of Sodium Chloride NaCl is 58.3 g/mol. So, you divide 1 mol over the Molar mass of NaCl which 58.3, and the answer you divide it by 100.
How many moles are in 10 grams of NaOH?
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.
How many sodium atoms are in a mole of sodium chloride NaCl?
If we mixed 58.5 grams of NaCl in a liter of water we would have a mole of NaCl per liter. ONE MOLE of any element has 6.023×1023 atoms of that element. Therefore 1 mole or 22.99 grams of Na = 6.023×1023 atoms of Na.
How many moles are in 2 grams of NaCl?
The answer is 58.44277. We assume you are converting between grams NaCl and mole. You can view more details on each measurement unit: molecular weight of NaCl or mol This compound is also known as Sodium Chloride. The SI base unit for amount of substance is the mole.
How many grams are in a 1.5 mole sample of sodium?
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Sodium, or 22.98977 grams.
What is the mass of 3.00 moles of NaCl?
The mass of 3 moles of sodium chloride is thus 175.32 g.
How many grams is in 1 mole of sodium?
And whereas one sodium atom has an approximate mass of 23 u, 1 mol of Na atoms has an approximate mass of 23 grams. One mole of a substance has the same mass in grams that one atom or molecule has in atomic mass units.

What is the mass of 3.75 moles of NaCl?
Mass of salt is equal to 218.8125 grams.
What is the mass of 2.5 moles of NaCl?
Answer: molar mass of NaCl is 58.5 gm/mol.
How do you find how many grams are in a mole?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
