Step-by-step explanation:
It is known that density is mass divided by volume in liter.
Mathematically, Density =

It is given that density is 3.51
and volume is 0.0270
.
Therefore, calculate the mass as follows.
Density =

3.51
=

mass = 0.09477 g
Thus, we can conclude that mass of given substance is 0.09477 g.
