The solution of which substance will hold 70 grams of substance for each 100 grams of water at 30 degrees?
The substance that will hold 70 grams for each 100 grams of water at 30 degrees Celsius is sodium chloride, commonly known as table salt. At this temperature and concentration, sodium chloride is fully soluble and forms a saturated solution.
How many grams of sodium chloride would be made if 46 grams of sodium completely reacted with 70 grams of chlorde?
The atomic or ionic mass of sodium is 22.99, and the atomic or ionic mass of chlorine is 35.45. A formula unit of sodium chloride contain one ion of each. Therefore, the mass ratio between sodium and chlorine in sodium chloride is 0.649. The mass ratio between 46 and 70 is 0.657. Therefore, chloride is the limiting reactant in this pair. The mass ratio of chloride to sodium chloride is 35.54/(22.99 + 35.54) or 0.607. Therefore, the mass of sodium chloride formed will be 70/(0.607) or 115 gm, where the depressed last digit indicates that it may not be accurate to + 1. (The limiting datum, 70, has only two significant digits.)
How many grams of chlorine gas are needed to make 117 grams of sodium chloride?
117 grams of sodium chloride (NaCl) is equivalent to 117 grams of chlorine gas because each molecule of NaCl contains one sodium atom and one chlorine atom.
Why is sodium chloride a useful starting material?
It is low cost and considerably abundant being in the ocean which covers 70% of the earths surface
What is the solubility of sodium iodide in water?
Very good, like all sodium salts. 178.8 g/100 mL (20 °C) 184 g/100 mL (25 °C) 294 g/100 mL (70 °C)
Will 600 g of sucrose dissolve in 300 mL of water at 70 degrees celsius?
Yes, 600g of sucrose will dissolve in 300mL of water at 70 degrees Celsius because at higher temperatures, solubility of most solids in liquids generally increases. However, it's important to note that solubility can also depend on factors such as stirring, agitation, and the purity of the substances.
How many grams of nacl would you dissolve in water to make a 50mM nacl solution with a 500mL of final volume?
Solubility increases with temperature, but the solubility of sodium chloride in water is 316 grams per litre at 0 degrees Celsius, and 330 grams per litre at 70 degrees Celsius. Since room temperature is somewhere between these two, this gives upper and lower limits of the solubility at room temperature. 50 grams of water has a volume of 50 cubic centimetres, or 0.05 litres. In one litre you could dissolve between 316 grams and 330 grams, so in 0.05 litres you could dissolve between 15.8 and 16.5 grams, where 15.8 = 316 x 0.05 and 16.5 = 330 x 0.05. So we can say it's around 16 grams of NaCl in 50 grams of water at room temperature.
What type of matter is sodium?
Sodium is an alkali metal element. It does not exist in it's elemental form on earth since it oxidizes quickly. It is highly reactive with water and a fiery explosion is often the result if the two come into contact.
What is the percent composition of chloride in 70 percent choline chloride?
35%

How warm is 70 degrees Celsius?
70 degrees Celsius = 158 degrees Fahrenheit.
