I assume the salt is the table salt type -- inactive. If true, the salt just dissolves and no chemical reaction results or heat generated. The mass will be the sum of that of the salt and water. Ans = 123 g.
It depends what beaker your talking about.
Condensation appears on the outside of a beaker when the temperature of the surrounding air is lower than the temperature of the contents inside the beaker. This temperature difference causes the moisture in the air to condense on the colder surface of the beaker, forming water droplets.
The total amount of water in the beaker was 0.5 liters (500 milliliters) + 300 milliliters = 800 milliliters.
The water in the beaker evaporated or was poured out.
There are more particles in the beaker with a large amount of water compared to a beaker with a small amount of water, assuming the water is the only substance present. This is because the volume of water in the larger beaker contains more individual water molecules than the volume of water in the smaller beaker.
it would be the same
Thirteen grams of water is the same as thirteen milliliters. So, if thirteen grams of water were added to the beaker, then thirteen milliliters of water were added.
It depends what beaker your talking about.
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.
This happens when the contents of the beaker are colder than the surrounding air. This causes water vapor in the warmer air to drop below its dew point and condense onto the outside of the beaker.
Somehow your data doesn't add up. The mass difference would be 195 - 125 = 70 grams. 1 ml of water weighs roughly 1 gram, so you would expect 70 ml of water to be filled into the beaker. Your water is either contaminated, extremely heavy or its a trick question.
The mass of undissolved potassium nitrate is cca. 3 g.
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.)
Condensation will collect on the outside of the beaker when you put a 5 ml of water and ice cubes inside due to the temperature difference between the cold contents inside the beaker and the warmer air outside. This causes water vapor in the air to condense, forming droplets on the exterior surface of the beaker.
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
