fijhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Explanation:
Answer:
19.29 g.cm⁻³
Solution:
Data Given:
Mass = 301 g
Volume = 15.6 cm³
Formula Used:
Density = Mass ÷ Volume
Putting values,
Density = 301 g ÷ 15.6 cm³
Density = 19.29 g.cm⁻³
The 3 parts are
1) A five carbon ribose sugar
2) A Phosphate molecule
3) The four nitrogenous bases
