Question

Какой объем занимает 40 грамм водорода Помогите срочно,пожалуйста

Answer 1

N=m/M
V=n*Vm (Vm-22.4 l/mol )
n(H2)=40g/ 2g/mol=20mol
V(H2)=22.4l/mol * 20mol=448 l

Answer 2

Volume of 40 grams of Hydrogen

The volume of 40 grams of hydrogen can be calculated using its molar mass and the ideal gas law. The molar mass of hydrogen is approximately 1.008 g/mol. The ideal gas law is given by the formula:

PV = nRT

Where: - P = pressure - V = volume - n = number of moles - R = ideal gas constant - T = temperature

To calculate the volume, we can rearrange the formula to solve for V:

V = (nRT) / P

Given that the molar mass of hydrogen is approximately 1.008 g/mol, we can calculate the number of moles using the formula:

n = mass / molar mass

Substituting the values into the formula, we can calculate the volume of 40 grams of hydrogen.

The search results did not provide a direct answer to the specific volume of 40 grams of hydrogen. Therefore, I will proceed with the calculation using the provided information.

Let's calculate the volume of 40 grams of hydrogen.
