Question
calculate the grams of 1.8% (m/m) NaCl solution that contains 8.00 g of NaCl
I tried 1.8 times 8.00g divided by 58.44g times 100 my answer is 24.6g rounded to 2 SF is 25g this truned out to be wrong I'm stumped!

m/m ? mass/mass?
if MassSolution*.018=massNaCl
then mass solution=8.00/.018
if MassSolution*.018=massNaCl
then mass solution=8.00/.018
