Answer:
Explanation:
You multiply the concentration (in moles per litre) by the volume in litres. The number of moles of a substance in one litre of solution is called its molarity. The official symbol for molarity is “c” (concentration), but most people use the symbol “M”. where n is the number of moles and V is the volume in litres
SrCO3
Sr=2 charge
CO3=2 charge from polyatomic chart
Answer:
Car B has a greater momentum than car A
Explanation:
Given data:
Mass of car A = 1200 Kg
speed of car A = 22 km/hr
Mass of car B = 1200 Kg
speed of car B = 25 Km/hr
Solution:
For car A:
p = mv
p = 1200 Kg × 22 km/hr
p = 26400 kg.km/hr
For car B:
p = mv
p = 1200 Kg × 25 km/hr
p = 30,000 kg.km/hr
