Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
What is the percentage of water in Sodium Sulfate Decahydrate?
55.91% The mass of NaSo4 is 142.05 plus the mass of 10 H2O molecules (180.16) is 332.21. Divide the mass o water overthe total mass to get .5591 or 55.91%
What mass of water must be added to 255.0g NaCl to make a 15.00 percent by mass aqueous solution?
To make a 15.00% by mass aqueous solution with NaCl, the mass of NaCl is 255.0g. This means that 15.00g of NaCl is present in every 100.00g of solution. To find the mass of water needed, first calculate the mass of NaCl in the final solution, then subtract this amount from the total mass of the solution (water + NaCl).
Calculate the percent by mass of water in the hydrated calcium sulfate salt?
Take the mass of the water lost and divide that number by the mass of hydrated calcium sulftate. Then multiply your answer by 100. For example: To find the amount of water, subtract the mass of the anhydrous sample from the hydated one like this: Mass of hydrated salt: 21.626 Mass of anhydrous salt: 21.441 21.626 - 21.441 = 0.185 (amount of water) To find the percentage of water, divide the water mass by the hydrated mass number: .185/21.626 = 0.00855 Now all you need to do is multiply your answer by 100 to get the percentage: 0.00855(100) = .8554% To see this last part algebraically, you can say, "what percent of the hydrated salt (21.626) is the mass of water (0.185)?" This would look like: x%(21.626)=0.185
What is the specific humidity formula used to calculate the amount of water vapor in a unit mass of air?
The specific humidity formula is: Specific Humidity Mass of Water Vapor / Total Mass of Air
A person has a pumpkin that has a mass of 4.8 kilograms If 0.9 of its mass is water how much of its mass is water and how much of its mass is not water?
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
A water tank has a mass of 3.64 kg when empty and a mass of 52.2 kg when filled to a certain level What is the mass of the water in the tank?
Full mass = 52.2 kgEmpty mass = 3.64 kgFull mass = (MT mass) + (water mass)52.2 = (3.64) + (water mass)Water mass = 52.2 - 3.64 = 48.56 kg
How do you find water by mass in a compound?
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.
What is mass of water?
The mass of water is 1g per cm3
Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
Why mass is measured as dry mass?
because when it contain water the mass of water will be the one to be obtained
Does liquid water have mass?
Yes, liquid water does have mass. If you have one litre of water - then you have one kilogram of water (weight/mass). The same applies for if you have twenty litres of water... you then have twenty kilograms of water.
Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
Does changing the mass of water change the mass of 1 cm3 of water?
No
If the gross mass of a can of water is 6.350 kg and in the can there are 5.5 liters of water what is the mass of the can in g?
Assuming that the water in the can is pure water (ie. with a specific gravity of 1) then the mass of the water in the can is 5.5kg (1L of pure water has a mass of 1kg), leaving the mass of the can to be 850g.
How do you explain how mass and energy are conserved when water evaporates?
When water evaporates, the water molecules gain energy from the surroundings to overcome intermolecular forces and escape into the air as vapor. While the water loses mass during evaporation, this mass is not lost but rather converted into the potential energy of the water vapor. Therefore, the total mass and energy of the system (water and surroundings) remains constant, demonstrating conservation of mass and energy.
What mass of water is 2.000 mol of water?
The mass of 2 moles of water is 36 g.
