6 A reaction between a solution of sodium carbonate is mixed with a solution of
calcium nitrate to cause a precipitation reaction. If 338.9 mL of 0.799 mol/L sodium
carbonate is added to 677.4 mL of 1.159 mol/L calcium nitrate, what is the mass (in
g) of precipitate that forms? Provide your answer to two decimals.

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.
