QuestionCalculate the mass: (4.3molL)(0.27 L)(139.76gmol)=(4.3 \frac{\mathrm{mol}}{\mathrm{L}})(0.27 \mathrm{~L})(139.76 \frac{\mathrm{g}}{\mathrm{mol}})=

Studdy Solution

STEP 1

Assumptions1. The molar concentration of the solution is4.3 mol/L. The volume of the solution is0.27 L3. The molar mass of the solute is139.76 g/mol

STEP 2

We are asked to find the mass of the solute in the solution. We can do this by multiplying the molar concentration by the volume and the molar mass.
Mass=MolarconcentrationtimesVolumetimesMolarmassMass = Molar\, concentration \\times Volume \\times Molar\, mass

STEP 3

Now, plug in the given values for the molar concentration, volume, and molar mass to calculate the mass.
Mass=(.3mol)(0.27 )(139.76gmol)Mass = \left(.3 \frac{\mathrm{mol}}{\mathrm{}}\right)(0.27 \mathrm{~})\left(139.76 \frac{\mathrm{g}}{\mathrm{mol}}\right)

STEP 4

Perform the multiplication.
Mass=(4.3mol)(0.27 )(139.76gmol)=162.47gMass = \left(4.3 \frac{\mathrm{mol}}{\mathrm{}}\right)(0.27 \mathrm{~})\left(139.76 \frac{\mathrm{g}}{\mathrm{mol}}\right) =162.47 \mathrm{g}The mass of the solute in the solution is162.47 grams.
