## Related Questions The formula is D = m / v first you must find mass of water. To find it just measure a beaker, then water in that beaker and subtract beakers mass. Then you have to find volume. You pour water in burette, and look how much is it. Finally dived mass by volume. The formula for calculating density is D=m/V. Density equals mass divided by volume. Calculate the volume of the cans, and then find the mass. Then find the mass of the coke and water in the cans. Subtract the mass of the cans so you're left with the masses of the coke and water. Put the masses and volumes into the formula. Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass There are 4 step to determine molecular formula, which are given bellow Step:1:- Find empirical formula Step:2:- Find empirical formula mass Step:3:- Find n n=molecular mass/empirical formula mass Step:4:- now find molecular formula to find molecular formula molecular formula(empirical formula)n If you know the molar mass of the compound, you have to calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula in order to find the ratio between the molecular formula and the empirical formula. Then multiply all the atoms by this ratio to find the molecular formula! You can find the answer if you just figure out the formula for mass. It also depends on what you are trying to find the mass of. (difference in water) x (mass of water) x (specific heat of water) x (1kc/ 10000c) molecular formula is referred to water because they are covalent compounds while formula mass for aluminum chloride because they are ionic compounds 1. Find the molar mass of the hydrate.Find the molar mass of the water molecules (18.01528 x # water molecules) and of the anhydrate; add the values together to find the molar mass of the hydrate.Molar Mass Water + Molar Mass Anhydrate = Molar Mass Hydrate2. Find the percent of water in hydrate.Divide the molar mass of water by the molar mass of hydrate; multiply by 100%.- Mass waterMass hydrate x 100% In order to find the volume of a liquid you first need to know its mass and density. You can then use the formula: volume = mass / density. For instance, if you have 2 kg of water, you can find out the volume that the water occupies. Water have a density of around 1kg/liter. We then use the mass/density formula:Volume = mass / density = 2 kg/(1 kg/liter) = 2 liter.We have now calculated that 2 kg of water occupies 2 liter of space, or 2 cubic decimeter (2 dm^3). To find the volume of an object use the formula v=dm where Volume=Density x Mass To find the mass of an object use the formula m=dv where Mass=Density x Volume 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  Density = mass / volume You can switch around the formula to look like: Mass = density * volume The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula. If you mean to find its molecular formula: 1. First you must obtain the empirical formula. Find the molar mass of the empirical formula. 2. The molar mass of the entire molecule must be given or its molecular formula cannot be find. 3. Put the molar mass given over the molar mass of the empirical formula. 4. Use this number (kind of like a scaler) to multiply by the entire empirical formula. This is the molecular formula.  The formula for finding that out is velocity = distance / mass The formula for density: density = mass / volume. Volume of a cube = edge3 You could then need to find the mass of the cube and substitute the values into the density formula. Find the mass of a known volume of the liquid and use the formula mass/volume to find the density.  you get a container and the amount of water you need and a whatever your going to use to measure the mass. first you find the mass of the container then you put the water in the cup and find the mass then subtract the mass of the cup from the mass of the cup and water then there's your answer.   u2/cm/g3 * * * * * I have no idea about the above answer, but it does not appear to answer the question. The best way to find the mass of a given quantity of water is to use a balance to find the mass of an empty container. Then pour the water into the container and measure their combined mass. The difference between the two is the mass of the water.
