To calculate the mass of water in a beaker by difference, first weigh the empty beaker and record its mass. Next, fill the beaker with water and weigh it again to obtain the combined mass of the beaker and water. Subtract the mass of the empty beaker from the total mass to find the mass of the water alone. This method allows for an accurate measurement by accounting for the container's weight.
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.
u2/cm/g3 * * * * * 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.
To calculate density using a 100mL beaker or cylinder, you would first measure the mass of the substance using a balance. Then, you would divide the mass by the volume of the beaker or cylinder to obtain the density. Density = mass / volume.
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.
The students needed to weigh the glass beaker first to determine its mass, which is essential for calculating the total weight of the water when combined with the beaker. By knowing the beaker's weight, they could subtract it from the total weight after adding water, allowing them to accurately measure just the weight of the water itself. This method ensures precise calculations and helps avoid errors in determining the water's mass.

it would be the same
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
32 g
The answer will depend on the capacity of the beaker. There is no information about that in the question.

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.

You must obtain and subtract the mass of the beaker.
It is necessary to know the mass of the empty beaker.
