Answer:
Option 2nd is correct
p = 7.7278 g/ml
Step-by-step explanation:
Formula for the density is given by:
\(p = \frac{m}{v}\) .....[1]
where,
p is the density
m is the mass
v is the volume
As per the statement:
If a substance has a mass of 27.82 grams and a volume of 3.6 ml
⇒\(m = 27.82 g\) and \(v = 3.6 ml\)
Substitute in [1] we get;
\(p = \frac{27.82}{3.6} = 7.72777778 g/ml\)
Therefore, the most accurate density of the substance in g/ml is, 7.7278
