How many moles are in 13.8 grams of sodium chloride?
Na is 23.0g and Cl is 35.5g which you add together to get the molar mass of the two is 58.5g/mole. Take the 13.8g of NaCl and divide it by the 38.5g will give you the moles: 13.8g NaCl(1 mole/58,5g)=. 236 moles of NaCl.
How many moles of NaCl are in sodium chloride?
Sodium chloride has a formula: NaCl, Sodium chloride, commonly known as salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. So, we can say that the number of moles associated with 1.17g sodium chloride is 0.02moles.
How do you calculate moles of NaCl?
One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.
How do you calculate grams to moles?
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.
How many moles are in sodium?
In grams, a mole is one formula mass. For example, 1 mol of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).
How many moles of sodium ions are in 117 g of NaCl?
Number of moles of ions = 2(2) = 4 moles of ions.
How many moles are present in 15 grams of sodium chloride?
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaCl, or 58.44277 grams.
