2.0 L
Answer:
Solution given:
no. of mole(n)=3.0mole
molarity(M)=1.5M
we have
<u>Volume of a substance is equal to the ratio of its no of mole to its molarity.</u>
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.
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration
Explanation:
37x - 1 + 23x + 1 = 180 ° { being co-interior angles }
60x = 180°
x = 180°/ 60
x = 3 °
Now
< T = 37x - 1° = 37 * 3° - 1 = 110°
Hope it will help :)
