How many atoms in compound NaCl?
Atomic mass of sodium = 22.99 Atomic mass of chlorine = 35.45 Total mass = 58.44g 58.44g of NaCl contains 6.023 x 1023 atoms ... 18.035g of NaCl contains 18.035x6.023x1023/58.44 = 1.858x1023 atoms!
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
What would you need to do to calculate molality of 10g of NaCI in 2Kg of water?
To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
What is the mass of a mole of Nac1?
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
Calculate the molar mass for the NaCl?
The molecular mass (not atomic mass) of sodium chloride is 58,44 g.
What is the mass of a mole of NaCl measured by?
The mass of one mole of NaCl is the sum of the atomic weights for sodium and chlorine in grams. The atomic weights are found on the periodic table.
How many atoms in compound NaCl?
Atomic mass of sodium = 22.99 Atomic mass of chlorine = 35.45 Total mass = 58.44g 58.44g of NaCl contains 6.023 x 1023 atoms ... 18.035g of NaCl contains 18.035x6.023x1023/58.44 = 1.858x1023 atoms!
How many moles of NaCl?
To determine the number of moles of NaCl, you need to know the mass of NaCl you have and the molar mass of NaCl (58.44 g/mol). You can then use the formula moles = mass / molar mass to calculate the number of moles of NaCl.
Why it is formula is NaCl?
NaCl is sodium chloride. NaCl2 doesn't exist up today.
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
What is the mass of NaCl formed?
The mass of the formula unit (NaCl) is formed from the sum of atomic weights of sodium and chlorine: 58,44 g.
How many moles are in 746g of NaCl?
Atomic mass of NaCl = 23.0 + 35.5 = 58.5 Amount of NaCl = 746/58.5 = 12.8mol
How many moles are in 20.0 grams of 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
What would you need to do to calculate the molality of 10 mol of NaCl in 200 mol of water?
Convert the 200 mol of water to kilograms of water.
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
