Answer:
Take 100 ml of a 18 molar solution. The total number of moles is (1 liter/1000 ml) 100 ml 18 moles is 1.8 moles.
1.5 moles in 1 liter so If 1.1 liters of water is added, the total volume is 1.2 liters and 1.8 moles are dissolves in it. 1.8 moles/ 1.2 liters is 1.5 moles per liter.
Answer: 19.4 g/cm3
Explanation: density is the relationship between mass over volume.
So density of gold is 15.7g/0.81cm3 = 19.4 g/cm3
Answer:
= 3132.9 Joules
Explanation:
- Kinetic energy is the energy possessed by a body when in motion.
- Kinetic energy is calculated by the formula; K.E = 1/2 mV², where m is the mass of the body or object, and V is the velocity.
- Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.
In this case;
Kinetic energy = 0.5 × 0.018 kg × 590²
<u>= 3132.9 Joules</u>
