The volume of the solid is
56.5 ml - 25 ml = 31.5 ml
The mass of the solid = 25g
So the density is Mass/ Volume
25/ 31.5 = 0.79 g/ml
Since the solid has a lower density (0.79 g/ml) than the density of water (1g/ml) it will float on water
Answer: Think and you will get it right!
Explanation:
To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.
Chromosomes have genes, and genes are segments of DNA.
