1 mmol sodium = 23 mg sodium chloride 80 mmol sodium chloride = 80 x 23= 1840 mg sodium chloride
About 265,000,000,000,000,000,000,000. (2.65 X 10^23)
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
Find out number of electron's in one mole of sodium ion? 1 mole of atoms = 6.02*10^23 atoms 1 mole of electrons = 6.02*10^23 electrons A Na atom has 11 protons and 11 electrons. Protons have a +1 charge and electrons have a -1 charge. A Na ion has 1 less electron than a sodium atom. One Na ion has 10 electrons. 1 mole of Na ions = 6.02*10^23 ions Each Na ion has 10 electrons. 1 mole of Na ions = 10 * 6.02*10^23 ions 1 mole of Na ions = 6.02*10^24 ions
3.33 x 10^23 sodium ions
sodium-11 has 5 proton,5 electron and 6 neutron. hahaha...miss-a--danq2,cia2,stephai,trinang!
The corresponding atom is sodium 23.
23
Atomic Weight sodium = 23 so 46/23 = 2 moles of sodium in 46.0g
An atom of Sodium weighs the same as 23 protons.
The mass of sodium is 22,91.10e-23 g.
1 mmol sodium = 23 mg sodium chloride 80 mmol sodium chloride = 80 x 23= 1840 mg sodium chloride
