What is the total number of molecules in 11.2 liters of N2 gas at STP

Chemistry
1 answer:
scoray [572]3 years ago
7 0
Molar volume at STP = 22,4 L

1 mole -------------- 22,4 L
 x mole -------------- 11,2 L

x = 11,2 / 22,4

x =  0,5 moles of N2

1 mole --------------- 6,02.10²³ molecules
0,5 moles ------------ y molecules

y = 0,5 . 6,02.10²³

y = 3,01.10²³ molecules

How can the mechanical advantage of a lever be increased?
valentina_108 [34]

The force or weight and distance on both sides of the fulcrum is given by the following ratio;

MA = Fb/Fa = a/b (MA = Mechanical Advantage)

The greater the distance from the fulcrum on which force is applied to lift a load on the other side of the fulcrum,  the less the effort required.
