A 5% sucrose solution has 5 grams of sucrose in every 100 grams of solution. As 1mL of water has a mass of 1 gram, you should dissolve 5 grams of sucrose in 95 mL of water.
1 M sucrose is 342.29 g in 1 L of water
1 mM sucrose= 0.3429 g
250 mM sucrose is 0.3429 * 250 = 85.87 g in 1 L of water
if preparing 100 ml of solution
for 1000 ml----85.87g
for 100 ml-----8.578 g
N should be M, meaning number of mole (N) per litre.
Concentration equals the number of mole per litre, or simply C=N/V.
We know the concentration is 0.1 mol/L
One mole of sucrose = 342g (from the molecular formula C12H22O11)
so 0.1 mol = 34.2g.
To make a 0.1 M sucrose solution, mix 34.2 grams of sucrose into every litre of water.
molarity (M) = moles/litre of solution
To make a 1.0 M sucrose solution, you need the molar mass of sucrose. C12H22O11
(12x12.0) + (22x1.0) + (11x16.0) = (according to wikipedia 342.30 g/mole)
Take the 342.20 grams of sucrose and put it into a graduated cylinder and then fill to the 1.0 L mark with water.
For 1 M Sucrose solution, 342g sucrose will be added in distilled water to make up the final volume to 1000ml. Therefore, for 0.25 ml, exactly one fourth, i.e., 85.5 g of sucrose will be added in distilled water to make up the final volume to 1000ml. This will result in the concentration of 0.25 M.
We can prepare it by taking 10 gram of sucrose in 100 ml of water.

.25 meters=250 mm
show solution convert 0.015 km to mm
a 12 inch rule is about 300 mm 300/12 x 10 = 250 Answer: about 250 mm
Dilute a measured volume of the 100 mM solution with 19 times its own volume of pure water to produce a 5mM solution.

pl. suggest how to prepare 50 sulphuric acid
I really dont know people
for prepare 1mM DPPH radical solution: DPPH Molecular weight: C18H12N5O6 = 394g DPPH 1mM = 394/1000= 0.394g/L
A water solution containing 50 mM tris(hydroxymethyl)aminomethane and 150 mM sodium chloride has a pH of 7,6.
250 mm = 25 centimetres.
1 m = 1000 mm 250 x 1000 = 250 000 mm
250 mm = 2.5 decimeters.
1000 mm = 1 m so 250 mm = 250/1000 = 0.25 metres. Simple!
.25 meters=250 mm
0.25 m = 250 mm
Yes. 25 cm = 250 mm
