A sample of water has a mass of 13 grams and volume of 13 milliters what is the density of water?
1 gm/ml
How many grams of oxygen are in 477 grams of water?
There are 424 grams of oxygen in 477 grams of water. 8 times 53 equals 424.
How much water is 300 grams of water?
300 grams of water is 300 ml , or 10.582 ounces
How much heat energy is absorbed in 65 gram sample whose temperature changed from 45 to 80 degrees celsius?
That completely depends on the specific heat capacity of the substance of which the sample is composed, which you haven't identified. It will take a lot more heat energy to raise the temperature of 65 grams of water 35 degrees than it would take to do the same to 65 grams of iron or yogurt, e.g.
What is the mass of water that weighs 4.5 grams?
4,5 grams
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
How many grams of water are needed to produce one hundred fifty grams of magnesium hydroxide?
A lot
The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
How much sodium chloride and other salts are dissolved in a water sample is the water's?
The concentration of salts dissolved in a water sample is referred to as salinity. Salinity is typically measured in parts per thousand (ppt) or in grams per liter (g/L) and includes sodium chloride, as well as other salts such as magnesium chloride and calcium sulfate.
What is the minimum amount of water that will dissolve 5 grams of magnesium sulfate?
The minimum amount of water required to dissolve 5 grams of magnesium sulfate would be approximately 72 mL at room temperature (25°C).
How do scientists measure the salinity ocean water?
count the grams of salt present in ever 1,000 grams of water
A silver white metal second in abundance to sodium in ocean water?
The metal you are referring to is magnesium. It is found in abundance in ocean water after sodium. Magnesium is a silver-white metal that is important for various biological functions and is commonly used in industries such as healthcare, automotive, and aerospace.
What causes differences in density of ocean water?
