Polyethylene oxide (PEO or EO) has a repeat unit molecular weight of about 44.05 g/mol (based on two hydrogen atoms, two carbon atoms, and one oxygen atom in each repeat unit). Assuming that your "0.3" is in grams, then the number of moles of EO would be calculated as: Number of moles of EO = mass (g) / molar mass (g/mol) = 0.3 g / 44.05 g/mol = 0.0068 moles (approximately) Sodium perchlorate (NaClO4) has a molecular weight of about 122.44 g/mol. If your "0.06" is also in grams, then the number of moles of Na would be calculated as: Number of moles of Na = mass (g) / molar mass (g/mol) = 0.06 g / 122.44 g/mol = 0.00049 moles (approximately)
The EO/Na ratio is calculated as the ratio of the moles of ethylene oxide (EO) units to the moles of sodium perchlorate (Na).
To calculate this, first, determine the moles of each component:
The ratio of EO/Na would then be:
EO/Na = 0.0068 / 0.00049 = ~13.88 (approximately)
Therefore, the EO/Na ratio in your system is about 13.88. Please ensure that the numbers "0.3" and "0.06" you provided are indeed in grams for this calculation to be accurate.
