Ethylene glycol (antifreeze) has a density of 1.11 g/cm3. What is the mass in grams of 385 mL of this liquid?
Makovka662 [10]
Cm^3 = mL

1.11 g/cm^3 = 1.11 g/mL

Density (g/mL) multiplied by volume (mL) will give us the mass (g)

1.11 g/mL * 385 mL = 427.35 g

And since we have 3 significant figures, we have 427. g.

What is the mole fraction of sodium chloride in solution that is 13. 0 y mass sodium chloride and that has a density of 1. 10 g/
lyudmila [28]

Mole fraction is the ratio of the constituent moles to the total constituents. The mole fraction of sodium chloride is 0.0443.

<h3>What is a mole fraction?</h3>

A mole fraction is the proportion of the moles of the component in a total component present.

In 100 gm of solution 13.0 5 means, there is 13.0 gm of sodium chloride present. The mass of water is calculated as,

100 - 13.0 = 87.0 gm

Moles of sodium chloride is calculated as:

\begin{aligned} \rm moles &= \rm \dfrac{mass}{molar\; mass} \\\\&= \dfrac{13}{58}\\\\&= 0.224 \;\rm moles\end{aligned}

Moles of water are calculated as:

\begin{aligned} \rm moles &= \rm \dfrac{mass}{molar\; mass} \\\\&= \dfrac{87}{18}\\\\&= 4.83\;\rm moles\end{aligned}

Now, moles fraction is calculated by dividing moles of sodium chloride by total moles as,

\begin{aligned} \text{Mole fraction of NaCl} &= \dfrac{0.224}{0.224 + 4.83}\\\\&= 0.0443\end{aligned}

Therefore, the mole fraction of sodium chloride is 0.0443.
