What is the formula of percent by volume and mass?
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100
What has a percent by volume of 0.038?
A solution with a percent by volume of 0.038 contains 0.038 liters of solute dissolved in 100 liters of solution. This means that 0.038% of the total volume is the solute.
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.
What is the formula for percent of concentration?
M = n / V M = concentration of solution in mol/L, n = moles of substance, V = volume of solution in litres (L) the formula can re-arranged to V = n / M :)
What information would you need in order to convert molarity to percent by volume?
To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.
How can you express the solution in percent by volume?
Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.
What is the difference of percent by mass and percent by volume?
Percent per mass is exprimed in g/Kg, mg/kg, µg/kg, etc. Ex.: An ore contain 10 mg gold/kg ore. Percent per volume is exprimed in volume to volume. Ex.: Vodka contain 40 volumes of ethanol/100 volumes of liquid.
What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
What is the formula for molarity in writin form?
The formula for molarity (M) is: moles of solute (in mol) / volume of solution (in liters). It can be written as: M = n/V, where n is the number of moles of solute and V is the volume of the solution in liters.
Could you calculate the molarity of a solution you need to know the moles of solute and the?
Molarity is calculated by dividing the moles of solute by the volume of solution in liters. The formula is Molarity (M) = moles of solute / volume of solution (in liters). It is important to have accurate measurements of both the moles of solute and the volume of the solution to determine the molarity.
What is the molarity of a solution with a percent concentration of a given solute?
To find the molarity of a solution with a percent concentration of a solute, you need to know the molecular weight of the solute and the density of the solution. Then, you can use the formula: Molarity (percent concentration density) / (molecular weight 100).
What is the percent by volume of a solution formed by mixing 25mL of isopropanol with 45 mL of water?
% V / V (percentage of volume per volume) =? V1 (solute volume) = 25 mL V (volume of the solution) = solute + solvent = 25 mL + 45 mL = 70 mL We apply the data to the formula of volume percentage of the solute per volume of solution, we will have:
