calculate the mass in gram of NaOH present in 250cm3 of 0.1mol/dm3 of its solution
The mass is 1.0grams. First you multiply the molecular weight and molarity which is 39.997g/mol x 0.1mol/dm3= 3.9997g/dm3. Then you convert dm3 to cm3. 1dm3 =1000cm3. In this case you would divide 3.9997 by 1000 which would give you 3.9997*10^-3 g/cm3. To get the mass you multiply 3.9997*10^-3 and

250cm3 and get the mass as .999925, with significant figures the answer is 1.0 grams

what's the difference between molecules and compounds
A compound can be a molecule however compounds must contain more than one element. For example ozone, O3 is a molecule but not a compound.
