Expert Answer:

2. Given:
Mass = 1.8 kg and
Volume = 250 cc = 250 cm3 =250 × 10-6 m3
We know that 
begin mathsize 12px style Density equals Mass over Volume
therefore Density equals fraction numerator 1.8 space kg over denominator 3250 cross times 10 to the power of negative 6 end exponent space straight m cubed end fraction
rightwards arrow Density equals 7200 space kg divided by straight m cubed end style
 
Note: kindly ask other questions as a separate query each.
