The molality equation also requires the moles of solute. The molarity describes 3.000 moles of NaCl per 1 L of solution. Use the moles of NaCl to solve for the mass of NaCl. Note: use the molar mass of NaCl rounded to 4 significant figures.

Answer : The mass of NaCl will be, 175.5 grams

Explanation : Given,

Moles of = 3.000 mol

Volume of solution = 1 L

Molar mass of = 58.5 g/mole

Formula used :

Thus, the mass of NaCl will be, 175.5 grams

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
