1 mL of water = 1 gram
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.
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.
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams and milligrams are measures of weight or mass.
To find the dissolving rate, you divide the time by the mass. --> 200s/5grams=40mL/s
25/40 = 0.625 grams per mL or 0.625 grams per cubic centimetre
One mililiter of water is approximately one gram.
okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass
how would you find the mass of 250 mL of water
To find water by mass in a compound, you can calculate the difference in mass before and after heating the compound to drive off the water. The lost mass represents the mass of water present in the compound. You can then calculate the percentage of water in the compound by dividing the mass of water by the total mass of the compound and multiplying by 100.
The pumpkin's mass is 4.8 kg, and 0.9 of its mass is water. This means 0.1 of its mass is not water. To find the mass of water: 4.8 kg x 0.9 = 4.32 kg of water To find the mass of not water: 4.8 kg - 4.32 kg = 0.48 kg of not water
To calculate the density of the saline solution, you will need to know its mass. If the mass is not provided, you can't determine the density just based on the volume. Density is calculated as mass divided by volume.
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
