Please explain!

Answer 1

Step-by-step explanation:

here's the answer to your question

Answer 2

2.0 L

Answer:

Solution given:

no. of mole(n)=3.0mole

molarity(M)=1.5M

we have

Volume of a substance is equal to the ratio of its no of mole to its molarity.

By this we get a relation:

Volume=no.of mole/molarity

substituting value

Volume=3.0/1.5=2

The required volume is 2 litre.
