The percentage of silver nitrate by weight is 100[5.48/(5.48 + 25.0)] = 18.0 %, to the justified number of significant digits.
The concentration of ethanol is 11,7 %.
500mg/l
The concentration of this solution (in NaOH) is 40 g/L.
Look up or calculate the molecular weight/molar mass of FeCl3. Then... 40.0 g FeCl3/MW FeCl3/0.275 L = M (concentration of FeCl3 in solution)
1 % DCPIP solution can be prepared by dissolving 1g of the dye in 100cm3 of water
The percent concentration is 13,75 %.
The answer is 0,0207 mol.
The concentration of ethanol is 11,7 %.
13,75 % NaCl
500mg/l
The concentration of this solution (in NaOH) is 40 g/L.
Solvent
You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution.
