Answer : 
Explanation : To convert amu i.e. atomic mass unit in grams we have the conversion factor as 1 amu = 
we know the mass of the proton is 1.0073 amu
So converting it into grams we have to multiply;
1.0073 amu X
= 
Now, Volume = 1/6πd³ as diameter is given as
converting it to cm will require to multiply with 100
∴ Volume = 1/6π
Hence, volume = 
Therefore, Density = mass / volume
∴ Density = 
Therefore, Density will be
.
a scale-model mound made of the same materials that make the real hill
Mass = ?
Density = 2.70 g/mL
Volume = 276 mL
Therefore:
D = m / V
2.70 = m / 276
m = 2.70 x 276
m = 745.2 g
