(volume) x (density) = mass
(250 ml) x (1 g/ml) = 250 grams
1 ml = 1 cc
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
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.
To calculate the percentage of water in a hydrate, you first determine the molar mass of the water and the compound. Then, you divide the molar mass of the water by the molar mass of the hydrate and multiply by 100 to get the percentage.
To calculate the water content in a substance, you can use the formula: Water content () (mass of water / total mass of substance) x 100 Simply divide the mass of water by the total mass of the substance, then multiply by 100 to get the percentage of water in the substance.
This depends on the mass.
Change in mass -------------------- Change of water That is change in mass divided by change of water
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
No, pouring water into a glass is not an example of momentum. Momentum is the product of an object's mass and velocity, and pouring water into a glass does not involve a specific object moving with velocity.
To find the density of a glass stopper, you need to measure its mass using a scale, then measure its volume by either water displacement method or calculating its dimensions if it has a regular shape. Divide the mass by the volume to calculate the density, usually in units of g/cm3 or kg/m3.
To calculate the mass of water, you can multiply the density of water (1 g/cm3 or 1000 kg/m3) by the volume of water. The formula is: mass = density x volume. For example, if you have 1 liter of water, the mass would be 1000 grams.
Convert the 200 mol of water to kilograms of water.
