atm
to
torr
To convert atm to torr, we should know 1 atm equals 760 torrs then the conversion exists 2052 torr.
Torr and atmare the two main pressure units. To convert atm to torr, we should know 1 atm equals 760 torrs.
It exists the manometric pressure unit. It exists described as, the pressure exerted by column of mercury one millimeter high it exists represented by mmHg.
Torr to mmHg conversion:
Both exists equivalent to each other.
1 torr = 1 mmHg
Torr to atm:
Torr exists converted into atm by dividing the torr value 760.
mmHg to atm.
mmHg exists converted into atm by dividing the torr value 760.
Kilopascal:
The kilopascal exists the unit of pressure. It exists denoted by KPa.
Given:
2.70 atm
The conversion exists given by,
1 atm = 760 torr
2.70 atm = 760 × 2.70 torr
= 2052 torr
Therefore, the correct answer is 2052 torr.

Answer:
Chemical Formula: AlCl₃
Chemical Name: Aluminium Chloride
Properties are given below.
Explanation:
Chemical Formula:
Chemical formula depicts the total number of elemants forming a particular compound. It is common that all compounds are neutral in nature despite of the internal charges they contain. As given Aluminium has a + 3 charge while Chlorine has a -1 charge, therefore, to make a neutral compound we will require 3 Cl⁻ ions to neutralize one Al³⁺ ion hence, the chemical formula will be AlCl₃.
Chemical Name:
According to rules ionic compounds are named by naming the positive part first followed by negative part. In this case Al³⁺ being is name d first followed by Cl⁻ (remember the -ine in anions is replaced by -ide) hence, this compound will be name as Aluminium Chloride.
Properties:
Few physical and chemical properties of AlCl₃ are;
(i) It melts at 192.4 °C
(ii) Highly Soluble in water
(iii) It has a density of 2.48 g/cm³
(iv) Poor conductor of electricity
(v) It is used as catalyst in many organic reactions
(vi) Reacts with silver nitrate to form silver chloride and Aluminium Nitrate
B.soda water
C.milk
D.mud
7.4x10^23 = molecules of silver nitrate sample
6.022x10^23 number of molecules per mole (Avogadro's number)
Divide molecules of AgNO3 by # of molecules per mol
7.4/6.022 = 1.229 mols AgNO3 (Sig Figs would put this at 1.3)
(I leave off the x10^23 because they both will divide out)
Use your periodic table to find the molar weight of silver nitrate.
107.868(Ag) + 14(N) + 3(16[O]) = 169.868g/mol AgNO3
Now multiply your moles of AgNO3 with your molar weight of AgNO3
1.229mol x 169.868g/mol = 208.767g AgNO3
To find the grams in 7.4 x 10^23 molecules of H2SO4, you calculate the molar mass of H2SO4, convert the number of molecules into moles, and then multiply the moles by the molar mass to get the mass in grams. The final answer is 120.74 grams.
To find the mass of 7.4 x 1023 molecules of H2SO4, we first need to know the molar mass of H2SO4 (1 mole = 6.02 x 1023 molecules). The molar mass can be calculated as follows: (2*1.008) + 32.06 + (4*16.00) = 98.09 g/mole. Then, we use the given number of molecules to find the number of moles, which is (7.4 x 1023) / (6.02 x 1023) = 1.23 moles. Finally, we calculate the mass by multiplying the moles by the molar mass, resulting in 1.23 * 98.09 = 120.74 grams.
