How much water must be added to 40 ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
1g of a drug is dissolved in 2.5mL of solution what is the percentage strength of the solution ww How do you calculate percent ww when 1g of drug is dissolved in 2.5mL of solution?
To calculate the weight/weight (ww) percentage strength of the solution, divide the weight of the drug (1g) by the total weight of the solution (1g drug + weight of solvent in 2.5mL). Since the density of most common solvents is close to 1g/mL, the weight of the solvent in 2.5mL would be around 2.5g. Therefore, the total weight of the solution would be 1g (drug) + 2.5g (solvent) = 3.5g. So, the ww percentage strength of the solution would be (1g / 3.5g) * 100% = 28.57%.
How many grams in 1 percent solution?
A 1% solution normally contains 1 gram of active ingredient per 100 ml of solution (weight-volume percent) Could also be 1gm per 100 gms (weight-weight percent)- but normally weight-volume is used.
Can one solution have a greater concentration than another in terms of weight percent but a lower concentration in terms of Molarity?
Yes, one solution can have a greater concentration in terms of weight percent while having a lower concentration in terms of molarity. Weight percent is based on the mass of solute relative to the total mass of the solution, while molarity is based on the number of moles of solute per liter of solution. If the solute has a high molar mass, a solution can have a high weight percent but a lower molarity compared to another solution with a lower weight percent but a solute of lower molar mass.
What information is necessary to determine the molarity of a solution if the chemical formula of the solute is known?
To determine the molarity of a solution when the chemical formula of the solute is known, you need to know the mass of the solute dissolved in the solution and the volume of the solution. From there, you can use the formula: Molarity = (moles of solute) / (volume of solution in liters) to calculate the molarity of the solution.
