need chemistry help please

[love]

ok im totally dumb when it comes to chemistry and completly have no understanding of it, any ways i have this assignment to complete and the question is :

In an experiment to determine the solubility of aspirin in ethanol it was found that 7.14g of aspirin could be dissolved in 50ml of ethanol at 20°C
(c) use the data to calculate the solubility of aspirin in ethanol in SI units and also its concentration in mmol per litre

please help

This means that 14.28 grms would dissolve in 100mls solvent. mmols are molecular weight in grms/litre so just multiply by 10 and then calculate MW of aspirin and do by simple proportion.
