A mass of 0.630 g of NaCl is dissolved in 525 g of water.
CAlculate the molality.
mass of NaCl= 0.630g
mass of H20= 525g
molar mass of NaCl= 58.44
This is what i did it keeps telling me the answer is wrong.
Convert grams to moles of NaCl
0.630 * 1 mol NaCl/58.44= 0.01078
Molality= moles of solute/ mass of
0.01078/ 0.0525 = 0.2053m NaCl
Can some one please double check where im going wrong
