Using the data
below, determine the stoichiometry of the hydrated calcium sulfate, CaSO4.2H2O
Please Note: Although I will normally be an integer, in this theoretical calculation, you should report
the value of 3 to the correct number of significant figures.
Data:
Mass of crucible=14.2100 g
Mass of crucible + gypsum=
15.6016 g
Mass of crucible + contents after heating= 15.2979 g

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
