Water is 88.8 percent by mass oxygen How many grams of water would contain 2.45 kg of oxygen?
I believe you would divide the kg by 88.8 to get 1%, then multiply by 100 to get the total mass. If you want it in grams then multiply by 1000. The answer ends up as 2759 grams. Feel free to correct me if you think I am wrong.
What is the mass of 250 mL beaker filled with 100 mL of water?
Well, darling, a 250 mL beaker filled with 100 mL of water would have a mass of approximately 100 grams. Water has a density of 1 g/mL, so 100 mL would weigh 100 grams. The beaker itself doesn't add any weight, unless you're counting the weight of your expectations.
What is the percent concentration by mass of a solution 4.2g of NaNO3 in 60 g water?
4.2 grams NaNO3/60 grams water * 100 = 7% by mass -------------------
Does 100 grams of uncooked chicken weigh more or less than 100 grams of cooked chicken?
it weighs the same. you specified that they both weigh 100 grams.ADDITION: Assuming 100 grams refers to mass, the uncooked chicken weighs .987 newtons.Cooked chicken will have a mass less than 100 grams. One reason is evaporation. A majority of the meats composition is made of water molecules. The evaporation of water will reduce the total mass of the chicken.
5.8 grams in 1 liter of water equals how many moles?
To convert grams to moles, divide the mass in grams by the molar mass of the substance. The molar mass of water is approximately 18 g/mol (1 g/mol for hydrogen and 16 g/mol for oxygen). So, 5.8 grams of water in 1 liter would be approximately 0.32 moles (5.8 g / 18 g/mol).

How do you calculate how many grams of water are produced from 22.1 grams of oxygen?
First find the percentage by mass of oxygen in water. The formula for water is H2O, showing that water contains two hydrogen atoms for every atom of oxygen. The gram atomic masses of hydrogen and oxygen are 1.00794 and 15.9994 respectively. Therefore, the percentage of oxygen in water is 100{15.9994/[15.9994 + 2(1.00794)]} or about 88.8 %, to the justified number of significant digits; the ratio of the maximum mass of water that can be made from a given mass of oxygen is 1/0.888 or about 1.126; and the answer to the question is this number multiplied by the stated mass of oxygen, or 24.9 grams, to the justified number of significant digits.
How many grams water are in 100 milliliters of water?
The answer depends on the temperature, but at room temperature (20 deg C), 100 ml of water would have a mass of 99.82 grams.
What is the mass percent concentration for 5 grams of salt in 75 grams of water?
5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%
What is the mass of 100 milimeters of water?
If you have pure water, standard temperature, and standard pressure,then 100 milliliters of water has 100 grams of mass.(Note: 'milliliters', not 'millimeters'.)
What is the mass of 100 ml water?
The mass of 100 ml of water is approximately 100 grams. Water has a density of 1 gram per milliliter, so for every 1 ml of water, the mass is 1 gram.
What ids the total mass of the solution when 5 gramme of salt desolved in 100 gramme of water?
The total mass of the solution is 105 grams, which is the sum of the mass of the salt (5 grams) and the mass of the water (100 grams). The mass of the solute (salt) and the solvent (water) are additive in a solution.
What is the mass of 100 millimeters of water?
The mass of 100 millimeters of water is approximately 100 grams. This is because the density of water is very close to 1 gram per milliliter. Therefore, 100 milliliters of water would weigh around 100 grams.
How much mass is in 100 ML of water?
Pure water, standard temperature and pressure, etc. Mass of 100 ml of water = 100 grams
What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
What is the maximum mass of potassium chloride that will dissolve in 100 grams of water?
the solubility of potassium nitrate in 70 degreesCelsius water is about 134 g KNO3 per 100 g water
If you boil 100g of water should the steam weigh more than 100 grams?
If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.
