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:
1
Step-by-step explanation:
32-24 gives you 8
So she only needs one.
Answer:
10.5 cm
Step-by-step explanation:
Volume = base area × height
798 = (9.5 × 8) × height
height = 798/76
height = 10.5
Answer: 3,017.5 cubic centimeters.
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each cd case:
Volume of a rectangular prism= length x width x height
Replacing with the values given:
V = 14.2 x 12.5 x 1 = 177.5 cubic centimeters.
Since there are 17 cases in the stack, we have to multiply the volume one case by 17.
177.5 x 17 = 3,017.5 cubic centimeters.
