This density is 1,0707 g/cm3 at 20 0C.
Yes, this is true.
There is 20mg of NaCl in 200mg of a 10% salt solution. To convert mg to g, divide by 1000: 20mg = 0.02g of NaCl.
If 10 is 10 molar for you, this is a saturated solution of NaCl.
No. Everything below 0.9% of NaCl is hypotonic and every solution with concentration over 0.9% is hypertonic solution. Isotonic solution (to blood) is the one that has 0.9% of NaCl, or some other concentration of another compound.
suspended in a solution with the following composition: 10% NaCl, 10% glucose and 40% albumin.
10 percent NaCl in distilled water is equivalent to 100 g/L NaCl.
In a 10% NaCl solution, which is a strong hypertonic solution, red blood cells would shrink and shrivel up due to the high concentration of salt outside the cell causing water to move out of the cell through osmosis, leading to cell dehydration and eventual cell death.
A 10ml solution of 10 percent means that there are 10 grams of solute in 100ml of solution. Therefore, in 10ml of this solution, there would be 1 gram of the solute, as 10% of 10ml is 1ml of pure solute, which weighs 1 gram if the solute's density is 1 g/ml.
% by weight in solution = = 100 * (weight solute) / [(weight solvent) + (weight solute)] = 100 * (weight solute) / [weight solution] = 100* 10 / [100 + 10] = 100 * 10 / 110 = 9.1%
it is hypotonicQuoting from someone else's reply to this question What_is_an_example_of_a_hypotonic_solution,"0.45% NaCl (half-normal saline solution); since normal saline is 0.9% NaCl, any solution less than 9% is hypotonic".Doesn't this mean that 10% is hypertonic?
To calculate the molarity of 10 g of NaCl in 2 kg of water, you would first need to convert the mass of NaCl to moles using its molar mass. Then, calculate the total volume of the solution by considering the density of water (1 kg = 1 L). Finally, divide the moles of NaCl by the volume of the solution in liters to determine the molarity.
When a potato strip is soaked in a 10 percent NaCl solution, it undergoes osmosis, where water moves out of the potato cells due to the higher concentration of salt outside the cells. This causes the cells to lose water, leading to shrinkage and the potato strip becoming bendable.
