A saturated solution is made by dissolving as much solute as possible in a solute. For example, add table sugar (solute) to a glass of water (solvent) until no more sugar will dissolve even with vigorous stirring. The undissolved sugar settles to the bottom of the glass.
hope it helps
1. To solve this question, you need to equalize the mass of solute for both solution. The calculation would be:
mass of solute= volume*concentration
mass1=mass2
volume1 * concentration1 = volume2 * concentration2
volume1 * 0.7%= 2L *(1000ml/L) * 0.2%
volume1 = 2000ml * (0.2%/0.7%)
volume1= 571.429 ml
2. Since you already have the volume of stock needed, you just need to subtract it from the total solution volume to count the number of solvents needed.
new solution volume= stock volume + diluting solvent volume
2L * 2000ml/L = 571.429ml + diluting solvent volume
diluting solvent volume= 2000ml- 571.429 ml= 1428.571ml
Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.

Hello, this is what u can write.
“An object moving with constant velocity must have a constant speed in a constant direction”
Hope this helps u :)
