Can u answer this Question
your are such the hell one
You need to convert to g/litres first. 40/1.5 is 26.6667g. The molecular weight of glucose is 180.156. 26.66667/180.156 is 0.148 molar.
2 moles in 2 liters means 1 mole in 1 liter - so it its molarity is 1.
(126)(1.3)=163.8 divide 163.8 by 450 = .364 which is the answer
The molecular weight of glucose is 180. Let's say that you intend to make 100 ml of 5M solution. Here is the formula that can help you out every time you are dealing with molarity. (X, which is the desired weight divided by the molecular weight) X (1000/100, which is the desired volume) = 5, which is the desired molarity. So, X/180 X 1000/100 = 5; then X = 90. You need 90 g of glucose to make a 5 M of 100 ml solution of glucose. Hope this is clear, Samba.
186g C6H12O6 Use a concentration formula. Molarity - moles of solute/liters of solution. molarity = 1 moles of solute= x liters= 1 solve the equation and x= 1. One mole of glucose is equal to 186 grams.

Molarity = moles of solute/Liters of solution Find moles glucose, which is molecular formula------C6H12O6 154 grams C6H12O6 (1 mole C6H12O6/180.156 grams) = 0.8548 moles C6H12O6 Molarity = 0.8548 moles C6H12O6/1 Liter = 0.855 M glucose ---------------------------
Find moles of glucose. 32.8 grams C6H12O6 (1 mole C6H12O6/180.156 grams) = 0.18206 moles C6H12O6 Molarity = moles of solute/Liters of solution M = 0.18206 moles C6H12O6/1.0 L = 0.18 M C6H12O6
2 moles in 2 liters means 1 mole in 1 liter - so it its molarity is 1.
4 mol over 0.800 kg
(126)(1.3)=163.8 divide 163.8 by 450 = .364 which is the answer
Yes; the solution called "Ringer's Lactate" is a mixture containing water, essential salts and electrolytes, and glucose.

Moles of glucose = 80g/180g/mol = 0.444 moleMolarity = 0.444/0.75L = 0.5926 M
15.8/180 is 0.08777778 moles in 169ml. divide by 169, x 1000 (per litre) is 0.5194M
This is the code of a solution used in medicine, containing 5 % glucose and 0,3 % sodium chloride.
