Chloroform is a liquid once used for anesthetic. What is the volume of 5.0 g of chloroform? The density of chloroform 1.49 g/mL
mario62 [17]

Answer:

3.3557047 mL

Explanation:

The density can be found using the following formula:

d=\frac{m}{v}

Let's rearrange the formula to find the volume, v.

d*v=\frac{m}{v}*v

d*v=m

\frac{d*v}{d} =\frac{m}{d}

v=\frac{m}{d}

The volume can be found by dividing the mass by the density. The mass of the chloroform is 5 grams and the density is 1.49 grams per milliliter. Therefore,

m= 5g \\d= 1.49 g/mL

Substitute the values into the formula.

v=\frac{5g}{1.49 g/mL}

Divide. When we divide, the grams, or g, in the numerator and denominator will cancel out.

v= \frac{5}{1.49}mL

v=3.3557047 mL

The volume of 5 grams of chloroform is 3.3557047 milliliters

He molecular formula mass of this compound is 180 amu . what are the subscripts in the actual molecular formula?
mezya [45]
I can't actually answer this one if the empirical formula is not given. Luckily, I've found a similar problem from another website. The problem is shown in the picture attached. It shows that the empirical formula is CH₂O. Let's calculate the molar mass of the empirical formula.

Molar mass of E.F = 12 + 2(1) + 16 = 30 g/mol

Then, let's divide this to the molar mass of the molecular formula.
Molar mass of M.F/Molar mass of E.F = 180/30 = 6

Therefore, let's multiply 6 to each subscript in the empirical formula to determine the actual molecular formula.
<em>Actual molecular formula = C₆H₁₂O₆</em>
