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:
20
Step-by-step explanation:
its a pattern. the top goes up by three's so if it goes from 12 to 30 the d8 should go to 20 because if you add 3 to 12 to get it higher than you add 2 to 8 to get it higher.
Answer:
Nothing

1. 21.6
2. 54
3.16.22
Step-by-step explanation:
1. 3(1.8)(4)
2. 7.5(1.8)(4)
3. (1.4)(4) + (5.9)(1.8)
Answer:
d=112
f=112
a=68
e=68
c=112
Explanation:
Each line is equal to 180 degrees so 180-68 is 112 f and a should be the same degree because of the way the line is slanted. E and c will be the inverse of d and 68.
