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.
Probably just one of the ways is to calculate the mass of an empty container.
Then, pour the water into the container and calculate the mass.
Then, subtract the empty container's mass from the mass when you put the water in.
There you have it. The mass of the water. TADA!
Multiply the volume of the water by its density. Water has a density of 1 kg per liter.
So, obviously, you cannot simply pour water onto a balance and weigh it. You'll need something to hold it in. Try a beaker.
Lets say that you want to find the mass of 100mL of water. Firstly, you'll need to weigh an empty beaker on a balance and record the mass. Next, pour 100mL of water into the beaker and weigh it again. Record the mass of beaker containing water.
So now you have the mass of the beaker and the mass of the beaker + water. You want to find the mass of just the water. Subtract the mass of the beaker from the mass of the beaker with water, and there you have it.
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 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.

The mass of the water would be 40g - 2g = 38g. The mass of the salt would be 2g.

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.

Convert the 200 mol of water to kilograms of water.
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.

To calculate the molality of a solution, you need to know the moles of solute (in this case, NaCl) and the mass of the solvent (water). First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality using the formula molality = moles of solute / mass of solvent in kg.
To calculate the mass of water, you can use the specific heat capacity of water which is 4.18 J/gΒ°C. The formula to calculate the mass of water is: mass = energy / (specific heat capacity * change in temperature). Plugging in the values, the mass of water involved would be approximately 50.1 grams.
The mass of the water would be 40g - 2g = 38g. The mass of the salt would be 2g.
The mass of water used in the first six minutes depends on the rate of flow of water. If we know the flow rate, we can calculate the mass using the formula: Mass = flow rate x time.
To calculate the molality of a solution, you need to know the moles of solute and the mass of the solvent in kilograms. First, calculate the moles of NaCl in 0.2 kg: moles = mass (g) / molar mass. Then, calculate the molality by dividing the moles of solute by the mass of solvent in kg: molality = moles of solute / mass of solvent in kg.
