Last option: Disproves or proves
Answer:
1 mole of carbon-12 has 6.02 x 1023 atoms. you need to know how many moles there are in 20 grams of carbon-12. One mole of anything is the same number of grams as the molecular mass, since the molecular mass of carbon-12 is 12, there are 12 grams in 1 mole of it, and therefore 20/12 = 5/3 moles in 20 grams
Answer:
Volume is directly proportional to absolute temperature.
Explanation:
Answer:
45.2 mL must be meausred for the experiment
Explanation:
The density of the acetic acid is 1.105 g/mL, so this data gives the information about how many grams are contained in 1mL of volume.
Notice that 1 mL = 1 cm³
Acetic acid Density = Acetic acid mass / acetic acid volume
1.105 g/mL = 50 g / acetic acid volume
Acetic acid volume = 50 g / 1.105g/mL ⇒ 42.5 mL
He answers is B It equals the rate of the formation of SO3
