If it's 10 units long then one unit must be 625/10 = 62.5.
Look up the four possibilities and see which has a molar mass of 62.5. For example, you know it can't be ethylene.
H2C=CH2 is 28. Glucose is C6H12O6 and that is 180 so it can't be that. You can finish.
A small section of a polymer chain, containing 10 repeating units, has a relative molecular mass of 625.
Which of the following monomers could have polymerised to form this chain?
ethylene
viyl chloride
styrene
glucose
