Asmall sack of sand has a density of 1.5 g/cm3 and a mass of 1500 g. how much space (volume) does the sand occupy? 750 cm3 2250 cm3 1000 cm3

1.5 = 1500g/Volume

Rearrange the equation:

Volume = 1500/1.5 = 1000

So your answer is 3. 1000 cm3

It's actually 1000 cm 3:

Proof:

You take the 1.5 and divide it by 1500 and you get 1000 cm 3

the dissolution of polymer can be thermodynamically described in 2 steps.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
