By definition, one mole would be the same as the Atomic Mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.
Na- 23.0
Cl- 35.5
NaCl- 58.5 grams in one mole
1 mole NaCl = 58.44g 0.1601mol NaCl x 58.44g NaCl/mol NaCl = 9.35g NaCl
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
Jessica should bring about 23.6 grams of sodium chloride (NaCl) to the laboratory, as 1 mole of NaCl weighs 58.5 grams. This is calculated by multiplying the number of moles by the molar mass of NaCl (0.40 moles * 58.5 grams/mole = 23.6 grams).
The molar ratio of Cl2 to NaCl is 1:2, so for every 1 mole of Cl2, 2 moles of NaCl are produced. To find the amount of NaCl produced from 13g of Cl2, first calculate the number of moles of Cl2 using its molar mass, then use the mole ratio to determine the moles of NaCl, and finally convert to grams of NaCl.
(7.6 g NaCl) (moles NaCl/58.44 g NaCl) (1 mole Na/1 mole NaCl) ( 22.99 g Na/mole Na) = 2.989 g Na or 3.0 g Na (significant figures) Steps: 1. Change everything to moles: use molar mass/molecular of NaCl 2. Find the molar ratio: since there are 1 Na in every NaCl, then the ratio of NaCl to Na is 1:1 3. Change moles back to grams: use the molar mass/molecular weight of Na 4. Watch out for significant figures! I hope this is right
145 grams NaCl (1 mole NaCl/58.44 grams)(1 mole Na +/1 mole NaCl)(6.022 X 1023/1 mole Na +) = 1.49 X 1024 ions of sodium =====================
1 mole NaCl = 58.44g NaCl0.48mol NaCl x 58.44g NaCl/1mol NaCl = 28g NaCl
The molar mass of salt (NaCl) is 58.44 grams per mole. Therefore, there are 58.44 grams in 1 mole of salt.
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
1 mole NaCl = 58.44g 0.1601mol NaCl x 58.44g NaCl/mol NaCl = 9.35g NaCl
1.946 moles NaCl (58.44 grams/1 mole NaCl) = 113.7 grams sodium chloride ======================
Molarity = moles of solute/Liters of solutionGet moles NaCl.58.44 grams NaCl (1 mole NaCl/58.44 grams)= 1 mole NaCl------------------Molarity = 1 mole NaCl/1 liter= 1 M NaCl========
Since the reaction involves the formation of sodium chloride (NaCl), the molar ratio of sodium to chlorine is 1:1. Therefore, if 10 grams of sodium reacts to form 35 grams of NaCl, then 35 grams of chlorine is also needed for this reaction.
Answer: The mass of NaCl is, 219.15 grams Explanation: Given, Moles of NaCl = 3.75 mole Molar mass of NaCl = 22.99 + 35.45 = 58.44 g/mole Formula used : Now put all the given values in this formula, we get the mass of NaCl. Therefore, the mass of NaCl is, 219.15 grams
The molecular weight of sodium (Na) is 22.99 grams. The molecular weight of chlorine (Cl) is 35.45 grams. Therefore, there are 58.44 grams in 1 mole of NaCl. So, in 3.25 moles of NaCl, there are 58.44 gr x 3.25 = 189.93 grams.
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
