6. A monobasic organic acid X has the composition 31.6% carbon, 5.3% hydrogen and 63.1% oxygen. a. What is the empirical formula of acid X?
b. An aqueous solution solution contains 11.4 g of X per dm. 20 cm of this solution required 30
cm² of 0.100 mol dm NaOH for reaction in a titration. Calculate the relative molecular mass of
the acid.

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
