The density of He is 1.79 x 10⁻⁴ g/mL
In other words in 1 mL there's 1.79 x 10⁻⁴ g of He.
To fill a volume of 6.3 L the mass of He required
= 1.79 x 10⁻⁴ g/mL * 6300 mL
= 11 277 * 10⁻⁴ g
Therefore mass of He required = 1.1277 g of He
Answer:
you never know but manifestation never hurts.
Answer:
The mass of objects remains constant throughout the universe. This is because an object is made of he same amount of matter (atoms), no matter where you take it in the universe. If you take an object from the Earth to the moon, only the weight will change.
Explanation:
Hello!
The genetic material of all organisms which is made up of two twisted strands in a double helix is called DNA (DeoxyriboNucleic Acid)
DNA is the basis of all genetic information. It contains all instructions for the development and functioning of all living organisms and some viruses. The main function of DNA is the long-term storage of information to build other cell components like Proteins and RNA. It is composed of two strands with 4 possible bases which are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
Have a nice day!
