Filtration can be used to separate mixtures based on the size of their particle.

Filtration is a method to separate different molecule based on size. Filtration mostly used to separate solid substance in a liquid. To separate the molecule, you will need a tools that have smaller holes than the molecule size.
The example of usage of this method would be when you try to remove a substance from homogeneous solution using filter paper. The size of water molecule will be smaller than the paper so the water can pass through. But if the solute size is larger than the paper pore, it will be held and form a residue.

Calculate the density of the aluminum cylinder with a diameter 0f 1.3 cm weighing 18 grams. Height of the cylinder is 5.2 Cm. Fi
Masja [62]

Answer:

Percent error = 3.7%

Explanation:

Given data:

Density of Al cylinder = ?

Weight of cylinder = 18 g

Diameter = 1.3 cm

Height = 5.2 cm

Actual density of Al = 2.7 g/cm³

Percent error = ?

Solution:

First of all we will calculate the volume of cylinder through given formula.

V = πr²h

r = diameter /2

V = 22/7 × (0.65 cm)²× 5.2 cm

V = 22/7 × 0.4225cm²× 5.2 cm

V = 6.89 cm³

Now we will calculate the density.

d = m/v

d = 18 g/ 6.89 cm³

d = 2.6 g/cm³

Percent error:

Percent error = measured value - actual value /actual value × 100

Percent error = 2.6g/cm³ - 2.7g/cm³ /2.7g/cm³  × 100

Percent error = 3.7%

Negative sign shows that measured or experimental value is less than actual value.

1) will water boil at 100 degrees celsius whether it has 20 mg or 200 mg of weight?
aleksley [76]

Answer:

yes water boils at 100 degree Celsius but the boiling point water is different at different place because of the altitude of that place. For example boiling point of water is 96 decree Celsius.

No the 2 solutions don't boils at same time. it's because of their volume.

if the volume is more then it takes more time to boli. and vice versa

Assume that the NO, concentration in a house with a gas stove is 150 pg/m°. Calculate the equivalent concentration in ppm at STP
jok3333 [9.3K]

Explanation:

It is known that for NO_{2}, ppm present in 1 mg/m^{3} are as follows.

                      1 \frac{mg}{m^{3}} = 0.494 ppm

So, 150 pg/m^{3} = \frac{150}{1000} mg/m^{3}

                       = 0.15 mg/m^{3}

Therefore, calculate the equivalent concentration in ppm as follows.

             0.15 \times 0.494 ppm

              = 0.074 ppm

Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
