262 mg to ml
There are 1000 ml in 1 litre So convert the litres to ml first by multiplying by 1000 and then add on the ml: 21 litre 523 ml = 21 x 1000 ml + 523 ml = 21523 ml
The only way you can convert 75 ml to 0.75 litre is to increase the 75 ml by tenfold to get to 750 ml = 0.75 litre. 75 ml x 10 = 750 ml = 0.75 litre.
125 ml 500(ml) * 0.05 = 25 25 / 0.20 = 125
convert 6 mg to ml
You move the decimal point 3 places left. 16 ml becomes 0.016 Litre
A 20% solution would mean 20 g of the substance in 100 ml of solution. To convert this to mg per ml, you would have 20,000 mg of the substance in 100 ml of solution. Therefore, in a 20% solution, there would be 200 mg per ml.
To calculate the concentration of the sucrose solution, you would divide the amount of sucrose (125 mg) by the total volume of the solution (500 ml) and then convert the units as needed: Concentration of sucrose solution = 125 mg / 500 ml = 0.25 mg/ml = 0.25 g/L
To convert Potassium chloride mEq to ml, you need to know the concentration of the Potassium chloride solution. Once you have the concentration in mEq/ml, you can use the formula: ml = mEq / concentration (mEq/ml). This will give you the volume in milliliters.
Use Avogadro's number
To convert make a dillute solution from a concentrated one, take the amount of moles needed for the final solution as mL of concetrated solution, and dillute with water until the desired volume is reached.
To find molarity (M) with mL, you need to know the volume in milliliters (mL) of the solution and the amount of solute in moles (mol). Molarity is calculated by dividing the moles of solute by the volume of solution in liters (L). You can convert mL to L by dividing by 1000. The formula for molarity is M = moles of solute / liters of solution.
To find the number of moles in the solution, first convert the volume provided to liters (115 mL = 0.115 L). Then, multiply the volume in liters by the molarity of the solution: 0.115 L x 0.652 mol/L = 0.075 moles. So, there would be 0.075 moles in 115 mL of a 0.652 M solution.
There would be 946 mg (2 mg/ml x 473 ml) of active ingredient in 473 ml of the solution. To convert milligrams to grams, divide by 1000, so 946 mg is equal to 0.946 grams in 473 ml of the solution.
To calculate the mass of medication in the solution, multiply the volume of the solution (500 ml) by the concentration of the medication (10%). Convert the percentage to a decimal by dividing by 100 (10% = 0.10). So, 500 ml x 0.10 = 50 grams of medication in 500 ml of a 10% solution.
To find the number of moles, use the formula: moles = Molarity (M) x Volume (L). First, convert 300 ml to liters by dividing by 1000: 300 ml / 1000 = 0.3 L. Then, calculate moles = 1.5 M x 0.3 L = 0.45 moles. Therefore, there would be 0.45 moles in 300 ml of a 1.5 M solution.
To calculate the molarity, first convert the mass of sodium nitrate to moles using its molar mass. Then, divide the number of moles by the volume of solution in liters (265 mL = 0.265 L) to get the molarity. The molarity of the solution is about 0.68 M.
