How many moles of NaCl are in 50 grams of NaCl?
0.855 moles
Na has an atomic mass of 23 and Cl is 35.5. So the Mr(NaCl)= 23 + 35.5 = 58.5. Putting all of this into our moles equation gives us the answer: moles= 50/58.5 = 0.855 moles (3sf).
How many molecules does a gram of NaCl contain?
A single unit of NaCl has a mass of 58.45 u; NaCl has a molar mass of 58.45 g. In each of these moles of substances, there are 6.022 × 1023 units: 6.022 × 1023 atoms of H, 6.022 × 1023 molecules of H2 and H2O, 6.022 × 1023 units of NaCl ions….Solution.
| 6 C = 6 × 12.011 | = 72.066 |
|---|---|
| TOTAL | = 180.155 g/mol |
How do you calculate NaCl molecules?
To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. First, convert the grams to moles using the molar mass and then use Avogadro’s number to find the number of molecules: This calculation tells you that there are 2.1 x 1022 molecules of NaCl in 2 grams of NaCl.
How many moles is Fe2O3?
The Mr value of Fe2O3 is equal to 2(56) + 3(16) = 160. We get that the number of moles of Fe2O3 is equal to 30/160 = 3/16 moles. Since for every mole of Fe2O3 there are 2 moles of Fe present, there are 3/16 * 2 = 3/8 moles of Fe present in 30g of Fe2O3.
How many moles are in 50g of caco3?
Calculate the number of moles in 50g CaCO3. ∴ 50 g of CaCO3 = (1100×50) ( 1 100 × 50 ) mole = 0.5 mole.
What is the mass of 8 moles of NaCl?
The mass of eight moles of sodium chloride is ≈500g .
How many moles is 50 ml of Naoh?
40 g of NaOH is equal to 1 mole. 1 g of NaOH will be equal to 1 40 moles….Known values.
