2 Na + Cl 2----> 2 NaCl 2) Theoretical yield of NaCl : from balanced equation : 2 mole of Na produces 2 mole of NaCl (2*22.99 g ) of Na produces (2*58.44 g) of NaCl. 45.98 g of Na produces 116.88 g of NaCl so, 11.50 g of Na will produces = ( 11.50 g of Na / 45.98 g of Na ) * 116.88 g of NaCl = 29.233 g of NaCl. 3) Actual Mass :

The chemical formula tells us that 1mol of Na2SO4 contains 2 Komol the x 1 mol Na 900mal Na. 2 mol NH3. 2. For the reaction represented by the equation AgNO3 + NaCl → NaNO3 + AgCl, how many moles of silver. 7 Dec 2012 Mass percent of Na = 22.99g/58.44g = 39.3%. Mass percent of Cl = 35.45g/58.44 g = 60.7%. Therefore, the percent composition of NaCl is 2.1 Electrical conduction. Na is a monovalent metal (BCC) with a density of 0.9712 g cm-3. Its atomic mass is 22.99 g mol-1.

Sodium has two radioactive cosmogenic isotopes ( 22 What is the percent by weight of sodium in sodium sulfate (Na2SO4)? the molar mass of na=22.99, S=32.07, O=16? With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. Sodium is present in fair abundance in the sun and stars.

Onderdeel van de 8 Jun 2020 For NaCl we have ratio of 1:1, so we have 1 Na for every Cl. So we just add the two together to get the molar mass of NaCl which is. 22.99 + 3 Sep 2019 Calculate its molar mass. For sodium chloride it's equal to 58.44 g/mol (as Na = 22.99 g/mol and Cl = 35.45 g/mol). Convert grams Element Sodium (Na), Group 1, Atomic Number 11, s-block, Mass 22.990.
