The mass of one atom or molecule of a substance is given in atomic mass units, also called Daltons (abbreviated D or Da). Thus one molecule of water has a mass of 18.015 atomic mass units, or 18.015 Daltons. The atomic mass unit is defined such that one mole of water weighs 18.015 g. Suppose a protein has a mass of 64 192 Daltons (or 64.192 kDa). What would be the mass of one mole of this protein? O A. A protein of 64 192 Da has a molar mass of 3.866 x 1028 g/mol. OB. A protein of 64 192 Da has a molar mass of 1.0 g/mol. O C. A protein of 64 192 Da has a molar mass of 18.015 g/mol. ● D. A protein of 64 192 Da has a molar mass of 64.192 g/mol. O E. This question can't be answered without knowing the number of atoms in the protein. O F. A protein of 64 192 Da has a molar mass of 6.4192 x 10-² g/mol. O G. A protein of 64 192 Da has a molar mass of 3.866 x 10²5 g/mol. OH. A protein of 64 192 Da has a molar mass of 64 192 g/mol.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
