Calculate the Molarity (M, moles solute / Liter of solution) of a solution that is made by dissolving 3.456 mmoles of Barium per
yan [13]
Since Molarity is moles per Liter, you will first need to convert the mL into L, which makes it 0.4321L. Next divide: moles on top, Liters on the bottom.
3.456 moles / .4321L = 7.998 M

Question 2 (2 points)
poizon [28]

Answer:

m_w=439.2g

Explanation:

Hello!

In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

\%m/m=\frac{m_{solute}}{m_{solution}} *100\%

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

m_{solute}=\frac{\%m/m*m_{solution}}{100\%}

Thus, by plugging in the data, we obtain:

m_{solute}=\frac{8.5\%*480g}{100\%}=40.8g

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:

m_w=m_{sol}-m_{solute}=480g-40.8g\\\\m_w=439.2g

Best regards!
