Answer:

The water soluble substance which absorb moisture from the air and then dissolve on the absorbed moisture to change into liquid taste are called deliquescent substances whereas the substances which absorb moisture from air but do not change their state are called hygroscopic substances.

Answer:

Hygroscopic substances absorb moisture from the air but do not dissolve in it, whereas substance that undergo deliquescence dissolves in the water vapour that is absorbed from the air, forming a liquid solution

An empty Erlenmeyer flask weighs 241.3 g. When filled with water (d = 1.00 g/cm³), the flask and its contents weigh 489.1 g. (a)

miskamm [114]

The answer is- Volume of flask = 247.8 $cm^3$ or 247.8 mL.

Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.

What is the formula of volume in terms of density?

Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-

$d = \frac{m}{V}$

Thus, volume can be expressed as-

$V =\frac{m}{d}$

Now, mass of empty flask = 241.3 g and the mass of (flask + Water) = 489.1 g.

Thus, mass of water = $489.1\ g- 241.3\ g = 247.8\ g$ .

Thus, mass of water = 247.8 g and density of water = $1.00\ g/cm^3$ . Its volume is calculated as-

$V = \frac{247.8\ g}{1.00\ g/cm^3}=247.8\ cm^3$

Hence, volume of flask = 247.8 $cm^3$ or 247.8 mL.

If 1000. ml of linseed oil has a mass of 929 g, calculate the density of linseed oil

Ierofanga [76]

0.929 g/ml Density in this case is defined as mass per volume. Or in other words, mass divided by volume. So you simply divide 929 grams by 1000 ml. Giving 929 g / 1000 ml = 929/1000 g/ml = 0.929 g/ml
