Answer: 1.1739*10²⁴ molecules

Explanation:

Using Avogadro's constant,

1 mole of any substance = 6.02*10²³ molecule/atom or particles.

Therefore 1.95 mole of water contains;

1.95 * 6.024*10²³ molecules = 1.1739*10²⁴ molecules.

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.1mole H2O =1.635⋅1024molec.

How are the digestive system and the urinary system similar?

Olenka [21]

Answer:

While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine. They are closely connected in controlling the amount of water in your body.

What pressure is exerted on the bottom of a 0.500-m-wide by 0.900-m-long gas tank that can hold 50.0 kg of gasoline by the weigh

Natasha_Volkova [10]

Answer:

1088.89 Pa

Explanation:

According to the Newton's second law of motion:-

$Force=Mass\times Acceleration$

Mass = 50.0 kg

Acceleration = g = 9.81 m/s²

So,

$Force=50.0\times 9.8\ kgm/s^2$

Force = 490 N

Area of the base = $length\times breath$ = $0.500\times 0.900$ m² = 0.45 m²

Pressure = Force/Area = $\frac{490\ N}{0.45\ m^2}$ = 1088.89 Pa

Chlorine is a toxic, corrosive, reactive gas. Which representation (structural formula, electron dot structure, or three-dimensi

DanielleElmas [232]

electron dot structure

Explanation:

Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.

The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
The chemical symbol represents the nucleus and all electrons except the valence ones.
The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
Chlorine has 7 valence electrons in its outermost shell.
It is made up of 3 lone pairs and 1 odd pair of electron.
The odd pair accounts for the reason why chlorine is very reactive.
It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.
