According to the question

»» The volume displaced by the pebble
= 0.82 - 0.75 = 0.07 L = 70mL

Now , the mass of the pebble = 150g

Therefore , density of the pebble is

$\bf{Density = \frac{mass}{volume} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf{= \frac{150}{70} } = 2.14$

Hence , the density of the pebble = 2.14 g/mL {required answer}
