What is the mass of five grams of NaCl?
The molar mass of an element is its atomic weight from the periodic table in grams. The molar mass of a compound is the sum of the atomic weights in grams of each element times the subscript for each element. The mass of 1 mole of NaCl = (1 x 22.989770g/mol Na) + (1 x 35.453g/mol Cl) = 58.443g/mol NaCl. 0.5mol NaCl x (58.443g NaCl/1mol NaCl) = 29g NaCl or 30g NaCl using significant figures.
How much Na is needed to produce a 5 grams of table salt?
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
Explain the following weight approximately 5 grams of NaCl to the nearest milligram?
5 grams of NaCl, or table salt, is equal to 5,000 milligrams. to convert grams to milligrams you simply multiply by 1,000.
What would be the molarity of a 5 percent NaCl solution?
To calculate the molarity of a 5% NaCl solution, you need to know the density of the solution. Once you have the density, you can convert the percentage to grams per liter. Then, using the molar mass of NaCl (58.44 g/mol), you can calculate the molarity using the formula Molarity = (mass of solute in g) / (molar mass of solute in g/mol) / (volume of solution in L).
What is 5 M of NaCl equivalent to?
5 M of NaCl is equivalent to 292,2 grams.
Calculate how many grams of NaCl is required to make 200.0 mL of a 0.125 M solution?
To calculate the grams of NaCl needed to make a 0.125 M solution in 200.0 mL, use the formula: moles = Molarity x Volume (L). First, convert 200.0 mL to 0.2 L. Then, calculate moles: 0.125 mol/L x 0.2 L = 0.025 moles of NaCl. Finally, convert moles to grams by multiplying by the molar mass of NaCl (58.44 g/mol): 0.025 moles x 58.44 g/mol = 1.46 grams of NaCl.
How many grams of 5.4 mol of NaCl?
the molar mass of sodium is 23 and chlorine is 35 so they add together to create 58 grams per mole. So 5.58g/58g=.0962 moles.
How many moles of 5grams of oxalic acid?
To calculate the number of moles in 5 grams of oxalic acid (C2H2O4), first determine the molar mass of oxalic acid, which is 90.03 g/mol. Then, divide the mass (5 grams) by the molar mass to get the number of moles. In this case, 5 grams is equal to approximately 0.055 moles of oxalic acid.
How many grams of sodium are in and 5 grams of NaCl?
The answer is 1,98 g sodium.
Explain ' weigh approximately 5 grams of nacl precisely to millligram'?
It means, weigh about 5 grams of NaCl, precisely, to the milligram. I don't really know how to make it much simpler than that. Maybe this will help. 5 grams is 5000 milligrams. The value you get for the sodium chloride you weigh out will probably be between 4900 and 51000 milligrams. Anywhere in that range is fine.
If 5 grams of NaCl is dissolved in 200 mL of water what is the NaCl concentration?
The answer is 29,22 g NaCl.
What is the mass of 0.5 mol of carbon atoms in grams?
The molar mass of carbon is 12.01 g/mol. To find the mass of 0.5 mol of carbon atoms, you would multiply the molar mass (12.01 g/mol) by the number of moles (0.5 mol) to get the answer, which is 6.005 grams.
