The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
The weight of 40ml of a substance depends on its density. To find out the weight in grams, you would need to know the density of the substance in question. Different substances have different densities, which will affect the conversion from volume (ml) to weight (grams).
The weight of 40ml of oil will vary depending on the type of oil. On average, 40ml of oil weighs about 36 grams.
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.

A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.

200ml of solution x 20% of alcohol = 40ml of alcohol..
25/40 = 0.625 grams per mL or 0.625 grams per cubic centimetre
To prepare 200ml of 80% glycerol solution, you would mix 160ml of glycerol (200ml x 80%) with 40ml of water. Calculations: 200ml x 80% = 160ml glycerol, and 200ml - 160ml = 40ml water needed. Mix the glycerol and water thoroughly to obtain the 80% glycerol solution.
The weight of 40ml of oil will vary depending on the type of oil. On average, 40ml of oil weighs about 36 grams.

1.3 oz. or 8 teaspoons
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
40ml = 0.07 of a pint
