To identify a liquid substance, a student determined its density. Using a graduated cylinder, she measured out a 45-mL sample of
nalin [4]

Answer:

Calculated density = 0.8555g/ mL

Probable identity = Toulene

Explanation:

First off, the substance choices are;

isopropyl alcohol (density 0. 785 g/ mL)

toluene ( density 0.866g/ mL)

So upon calculation, if the density of the liquid substance is equal to either of the substances in the choice, it is that substance.

The relationship between density, mass and volume is given as;

Density = Mass / Volume

Mass = 38.5g

Volume = 45ml

Density = 38.5 / 45 = 0.8555g/ mL

Calculated density = 0.8555g/ mL

Among both substances, it is closest to  toluene ( density 0.866g/ mL).

Probable identity = Toulene

What is the mass in grams of 5.90 mol C₈H₁₈
Kitty [74]

Answer:

672.6 grams

Explanation:

molar mass of 1 mol of C₈H₁₈ = 114 grams

so mass of 5.9mol of C₈H₁₈ = 114* 5.9= 672.6 grams

Automobile battery acid is 38% H2SO4 and has a destiny of 1.29g/ml. Calculate the molality and the molarity of this solution. ​
baherus [9]

Answer:

M=5.0M\\\\m=6.2m

Explanation:

Hello,

In this case, 38 % is commonly a by mass concentration, meaning that we have 38 grams of solute (sulfuric acid) per 100 grams of solution (water+sulfuric acid):

38\%=\frac{m_{H_2SO_4}}{m_{H_2SO_4}+m_{H_2O}}

Hence, we compute the moles of sulfuric acid in 38 grams by using its molar mass (98 g/mol):

n_{H_2SO_4}=38g*\frac{1mol}{98g}=0.39mol H_2SO_4

Next, the volume of the solution in litres by using the density of the solution:

V_{solution}=100g*\frac{1mL}{1.29g}*\frac{1L}{1000mL} =0.0775L

This is done since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in litres, thus we have:

M=\frac{n}{V}=\frac{0.38mol}{0.0775L}=5.0M

On the other hand, the molality is defined as the ratio of the moles of the solute to the mass of the solvent in kilograms, thus, we compute the mass of water (solvent) as shown below:

m_{H_2O}=100g-38g=62g*\frac{1kg}{1000g}=0.062kg

So compute the molality:

m=\frac{n_{solute}}{m_{solvent}}=\frac{0.39mol}{0.062kg}=6.2m

Regards.
