Why did you measure the mass of the graduated cylinder at the beginning of the experiment and not after the liquid was poured out?
The mass of the graduated cylinder was measured at the beginning of the experiment to determine the empty weight of the container before any other substances were added to it. This allowed for the accurate calculation of the mass of the liquid poured into the cylinder by subtracting the initial empty mass from the total mass measured after the liquid was added.
What is the significance of "da" in chemistry and how does it relate to the measurement of atomic mass?
In chemistry, "da" stands for Dalton, a unit used to measure atomic mass. It represents the mass of one atomic particle, which is approximately equal to the mass of a proton or neutron. The atomic mass of an element is measured in Daltons, which helps scientists determine the relative mass of different atoms and molecules.
What is law of consevation of mass with experiment?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; it is simply rearranged. An experiment to demonstrate this is burning a piece of paper: the mass of the paper before burning will be the same as the mass of the ashes, smoke, and gases produced after burning. This experiment confirms that the total mass before and after the reaction remains constant.
What does gmm stand for in chemistry?
It stands for molar mass. You simply add the mass numbers of each element to get a total. So, for O2, the answer would be 16+16 (because there are two oxygens) and the total is 32.
How can you calculate the volume of H2O needed for a specific experiment?
To calculate the volume of water (H2O) needed for a specific experiment, you can use the formula: Volume Mass / Density. First, determine the mass of water required for the experiment. Then, find the density of water, which is approximately 1 gram per milliliter. Divide the mass by the density to calculate the volume of water needed.
What is a balance used for in chemistry?
A balance is used in chemistry to measure the mass of substances with precision. It helps chemists accurately determine the amount of reactants and products in a chemical reaction, ensuring the experiment's success and reproducibility. By using a balance, chemists can follow stoichiometry calculations and determine the correct proportions of substances.
What is an experiment in which the total mass of the starting material equals the total mass of the product?

What is An experiment you could carry out to determine the energy content of a seed?
To determine the energy content of a seed, you can perform a calorimetry experiment. First, dry a known mass of seeds and then burn them completely in a calorimeter, which is a device that measures the heat released during combustion. By measuring the temperature change of the water in the calorimeter, you can calculate the energy released per gram of seed. Finally, use the heat capacity of water and the mass of water used to determine the total energy content of the seeds.

Is the total mass of all chemical reactions less than the total mass of the reactants?
No, the total mass of all chemical reactions remains constant and is equal to the total mass of the reactants. This is known as the principle of conservation of mass in chemistry. Any perceived changes in mass during a chemical reaction are due to the rearrangement of atoms, not a loss or gain of mass.

What type of balance would you use to determine the approximate mass of the beaker?
Any type of balance having the accuracy needed for your experiment.
Determine the percent sulfur by mass in so3?
To determine the percent sulfur by mass in SO3, you need to consider the molar mass of each element. In SO3, there is one sulfur atom with a molar mass of 32.06 g/mol and three oxygen atoms with a molar mass of 16.00 g/mol each. Calculate the total molar mass of SO3, then determine the mass contributed by sulfur in that total mass to find the percent sulfur by mass.
