Mass of calcium carbonate (in grams) can be dissolved by 4.1 g of Hcl is 5.62g.
<h3>What is balanced equation?</h3>
A balanced equation is one for a chemical reaction in which the overall charge and the number of atoms for each component are the same for both the reactants and the products. In other words, the mass and charge of both sides of the reaction are equal.
The reaction between calcium carbonate and hydrochloric acid can be expressed through the chemical reaction,
CaCO₃ + 2HCl --> CaCl₂ + H₂O + CO₂
Hydrochloric acid has a molecular weight of 36.45 g/mol compared to calcium carbonate's molecular weight of 100 g/mol. According to the equation above, 72.9 g of hydrochloric acid may dissolve 100 g of calcium carbonate.
x = (4.1 g HCl)(100 g CaCO3 / 72.9 HCl)
x = 5.62 g.

The question is incomplete. Complete question is:
<span>All of the following containers have the same volume and temperature, which container has the most molecules
container 1-25.0 atm
container 2-50.0 atm
container 3- 12.5 atm
container 4- 1.00 atm
...........................................................................................................................
From, ideal gas equation, we know that PV = nRT
Thus, number of moles of gas depends on pressure, volume and temperature. Since, volume and temperature are held constant. number of moles of molecules will depends only on pressure of gas.
From above equation is can be seen that n </span>α P. Thus higher the pressure, more will be the molecules.
∴ In present case, container 2 will have <span>most molecules, as it has maximum pressure. </span>

Answer:
How do you calculate the average atomic mass of three isotopes?
To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses

Hey there!
This is a convergent boundary. Here, a oceanic crust collides with a continental crust.
Hope this helps :)
