A large synthetic polymer complex is made up of 333 identical copolymer chains.
The entire complex has an approximate relative formula mass (MrM_rMr) of 270,000,000,000270,000,000,000270,000,000,000.
What is the approximate relative formula mass of the polymer complex written in standard form?
What is the approximate relative formula mass (MrM_rMr) of each of the 333 individual copolymer chains?
