Astudent mixed two clear liquids together in a beaker.
a gas and a new liquid were formed . the gas escaped, so the student was unable to measure the mass. she guessed that its mass was more than 10.0 grams. here data is below:
liquid reactant a- 22.0
liquid reactant b- 9.0
liquid product- 17.2
gas product- ?

is the students guess about the mass of the gas correct?
a- yes, the actual mass is 4.8 g.
b- yes, the actual mass is 9.0 g.
c- no, the actual mass is 13.8 g.
d- no, the actual mass is 17.2 g.

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.
