Answer with Step-by-step explanation:
Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)
Thus we have
1 mole of sand = sand particles
Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is
Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of trillion sand particles is
Part 2)
Since it is given that volume of 1 sand particle is thus the volume of 1 mole of sand is volume of
sand particles
Thus volume of 1 mole is
Now since the Area of united states is
Thus the depth of the sand pile is
Answer: 65,780
Step-by-step explanation:
When we select r things from n things , we use combinations and the number of ways to select r things =
Given : The total number of playing cards in a deck = 52
The number of different five-card hands possible from a deck = 2,598,960
In a deck , there are 26 black cards and 26 red cards.
The number of ways to select 5 cards from 26 cards =
Hence, the number of different five-card hands possible from a deck of 52 playing cards such that all are black cards = 65,780
