If your working with cells, you want to be using saline instead of water to prevent osmosis. Also, you can use it as an electrolyte.
The answer is 0,9 g pure, dried NaCl.
The answer is 26,3 g.
Isotonic. A 0.9% NaCl solution is isotonic to red blood cells, meaning it has the same osmotic pressure as the cytoplasm of the cells, and therefore will not cause them to shrink or swell.
You need 841,536 g NaCl.
Water and salt form a solution, not a mixture. All solutions of NaCl in water are "salt water," but if you get the concentration of NaCl over 3.5 percent they prefer to use the term brine.
The Molecular Weight of NaCl = 58.5 So to make 1L of 4M NaCl solution you need 4*58.5=234g of NaCl So to make 100mL of the above solution you need 23.4 grams of NaCl
To convert moles to grams, use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 6.5 moles of NaCl would be 6.5 moles x 58.44 g/mol = 379.26 grams of NaCl.
To convert moles to grams, you need to use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 1.6 mol of NaCl would be equal to 1.6 mol * 58.44 g/mol = 93.504 grams of NaCl.
To determine this, you need the concentration of the NaCl solution. Once you have that, you can use the stoichiometry of the reaction between AgNO3 and NaCl to calculate the volume of 0.117 M AgNO3 needed. The balanced chemical equation for this reaction is: AgNO3 + NaCl → AgCl + NaNO3.
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.
Most use a .045 gap.
Oh honey, it's not rocket science. Just measure out 30 grams of table salt and dissolve it in enough water to make 100 grams of solution. Voila, you've got yourself a 30% NaCl solution. Just don't go drinking it thinking it's a margarita, okay?
