Answer:
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. . You divide the mass by the volume and compare the density to a list of known densities.
The correct answer is 1.6 × 10¹⁰ .
The volume of ice chunk can be calculated by using the formula length × breadth × height
The length of the ice chunk given is 98 m, the breadth of the ice chunk given is 25 m and the thickness of the ice chunk given is 750 m,
= 98 × 25 × 750 × 0.000189
= 347.9 m³
= 3.831 × 10¹⁴ gal
Water in swimming pool is 24000 gal
Therefore, number of pools that can be filled = 3.831 × 10¹⁴ / 24000
= 1.596 × 10¹⁰
= 1.6 × 10¹⁰
D, forms from decomposed material
