7. while prospecting in the north woods, joe found a gold nugget which had a density of 19.2 g/cm3. joe dropped the gold into water in a graduated cylinder, the water level increased by 15.0 ml. how many grams of gold did he have? (ans: 288 g)

Explanation:

1) Data:

a) d = 19.2 g/cm³

b) ΔV water = 15.0 ml

c) m = ?

2) Principles and formula:

        d = m / v

3) Solution:

a) v = ΔV water = 15.0 ml = 15 cm³

b) d = m / v ⇒ m = d × v = 19.2 g/cm³ × 15 cm³ = 288 g.

explanation:

i think option no d is the correct answer
