Dissolve some NaCl in water and add it up to 250 mL.
Crema acquosa is an Italian equivalent of the English phrase "acqueous cream."Specifically, the feminine noun crema means "cream." The feminine adjective acquosa translates as "acqueous." The pronunciation will be "KREH-ma-KWO-sa" in Italian.
To prepare 250ml of a 2M potassium chloride solution, measure out 17.8g of potassium chloride and dissolve it in water to make a total volume of 250ml. Make sure to stir the solution well to ensure the potassium chloride is completely dissolved. Then, adjust the final volume to exactly 250ml by adding more water if needed.
250ml of milk = 250ml of milk 250ml of milk = roughly 256g of milk 250ml of milk = roughly 1 cup plus 2/3 of a tablespoon
There are 7.56 250ml units in 1.89 liters.
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
By the definition of molarity, which is mass of solute in moles divided by solution volume in liters, 250 ml of 0.15 M NaCl* solution requires (250/1000)(0.15) or 0.0375 moles of NaCl. Each liter of 2M NaCl solution contains 2 moles of NaCl. Therefore, an amount of 0.0375 moles of NaCl is contained in (0.0375/2) liters, or about 18.75 ml of the 2M NaCl, and if this volume of the more concentrated solution is diluted to a total volume of 250 ml, a 0.15 M solution will be obtained. _________________ *Note correct capitalization of the formula.

If you need to make just 100mL, then you need 1 tenth of a liter that is 5M. If you were to make 1L of 5 molar NaCl, you would need 5 times the molar mass of NaCl (58.44g/mol) dissolved in 1L of water. Thus for 1L of a 5M solution you need 5 * 58.44g, or 292.2 grams of NaCl. However, since we only want 100mL, which is 1/10 of a Liter, we also only need 1/10 the amount of NaCl, or 292.2 / 10, which is 29.22g. So, measure out 29.22g NaCl, and dissolve completly in a volume less than 100mL, say 80mL, then bring the final volume up to 100mL. You now have 100mL of a 5M NaCl solution.
cup is 250ml therefor not even one
0.4
It varies from 226 to 250ml.
The answer is 0,9 g pure, dried NaCl.
