A0.3000-g sample of soda ash (which contains sodium carbonate) is dissolved in 50.00 ml of water. titration with standard 0.1000 m hcl required 42.70 ml of the acid to neutralize the soda ash solution. what is the percent by mass of sodium carbonate in the soda ash sample? the molar mass of sodium carbonate is 105.99 g/mol. the equation for the reaction of sodium carbonate and hydrochloric acid is

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.
