Chemistry
1 answer:
RSB [31]2 years ago
3 0

Answer:

Mass = 5.92 g

Explanation:

Given data:

Volume of O₂ = 4.15 mol

Temperature and pressure = standard

Mass in gram = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

By putting values,

1 atm × 4.15L = n ×0.0821 atm.L /mol.K × 273.15 k

4.15 atm.L = n ×22.43 atm.L /mol

n = 4.15 atm.L / 22.43 atm.L /mol

n = 0.185 mol

Mass in gram:

Mas = number of moles × molar mass

Mass = 0.185 mol ×32g/mol

Mass = 5.92 g

The model after John Dalton's was J.J Thompson's plum podding model in 1897, which described electrons as dots or raisins(if you will) in a circle shaped pudding that was entirely positive using a Cathode Ray Tube(shot cathode rays between magnets). The model after that is the Niels Bohr model in 1913, which depicts atoms like positively charged center called the nucleus with negatively charged particles called electrons in a shell or cloud.

Which of these is the smallest volume 500mL, 2,500 cm3, 5.5•10-1, 25 m3
mezya [45]
25m³.
500mL = 500cm³
25m³ = 2,500cm³
5.5x9 = 49.5(cm³)
25m³ is the smallest among the others.

Chemical weathering processes do not alter the chemical structure of minerals in rocks. *
Anna007 [38]
I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:

How to calculate moles
blondinia [14]

Explanation:

First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.

For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
