How many ml of 1 M stock solution of Na Cl are needed to prepare 200 ml of a 0.05 M solution?
Molartiy = moles of solute/Liters of solution200 mL X (1 Liter/10^2)= 0.200 Liters0.200 Liters x (0.05 M)= .01 moles of NaOH.01 moles of NaOH x (40 g NaOH/ 1 mole NaOH)= 0.4 g NaOH are required
What would need to be done to calculate the molarity of 10 g of NaCl in 2 kg of water?
10 g of NaCl in 2 kg of water is 5 g of NaCl in 1 kg of water.The molar mass of NaCl is 39,666 g.5 g is equal to 0,318 molal.
If A semipermeable sac containing 4 percent NaCl 9 percent glucose and 10 percent albumin is?
suspended in a solution with the following composition: 10% NaCl, 10% glucose and 40% albumin.
How many moles are in 8.4 x 1023 formula units NaCl?
8.4 X 10^23/6.022 X 10^23 = 1.4 moles NaCl
In a reaction between sodium and chlorine 10 grams of sodium is needed to prepare 35 grams of sodium chloride How many grams of chlorine is needed for this reaction?
Balanced equation first. 2Na + Cl2 -> 2NaCl 35 grams NaCl (1 mole NaCl/58.44 grams )( 1 mole Cl2/2 mole NaCl )( 70.9 grams Cl2/1 mole Cl2) = 21 grams of Cl2 needed
How do you prepare 0.1mM 0.3mM and 1mM from 10mM of NaCl?
You have to dilute the 10 mM NaCl 100X, 33,333X and 10X (X means "times") e.g. 100X: mix 10 ml of 10 mM Nacl with 990 ml of water (= 0,1 mM) 33,333X: mix 30 ml of 10 mM NaCl with 970 ml of water (= 0,3 mM) 10X: mix 100 ml of 10 mM NaCl with 900 ml of water (= 1 mM)
10 percent NaCl in distilled water?
10 percent NaCl in distilled water is equivalent to 100 g/L NaCl.
How many 10 are in 100?
Approximately 10 of them.
How do you prepare 10 percent Na2CO3 solution?
Mix 100 mL of a 1 N solution with 900 mL of distilled water.
How many cups in 50 lbs of sugar?
That is approximately 10 cups.
In a 10 NaCl solution is NaCl a colloid?
If 10 is 10 molar for you, this is a saturated solution of NaCl.
What is the percent by weight of a solution prepared by dissolving 10 g of NaCl in 100 g of H2O?
% 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%
Does a pen weigh 10 grams or 100 grams?
A pen would weigh approximately 10 grams. 100 grams would be about 100 grams of feathers.
How do you prepare a 500mL of 1M of NaCl solutuion?
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.
What is 99 rounded to the nearest 10?
100
How many liters are there in 100 grams milk?
That is approximately 1/10 of a litre
