How do i set up the equation for this question on the moles of chalk lab. how many pieces of chalk would you need to have a mole of chalk?
To set up the equation for the moles of chalk, you first need to determine the molar mass of the main component of chalk, which is calcium carbonate (CaCO₃). The molar mass is approximately 100.09 g/mol. Then, find the mass of a single piece of chalk, and divide the molar mass by that mass to calculate how many pieces of chalk are needed to equal one mole. The equation can be expressed as: Number of pieces = (100.09 g/mol) / (mass of one piece of chalk in grams).

How many moles of nh3 are produced from 1.5 moles h2?
The balanced chemical equation for the reaction is: 3H2 + N2 -> 2NH3 From the stoichiometry of the balanced equation, 3 moles of H2 produces 2 moles of NH3. Therefore, if you have 1.5 moles of H2, you will produce 1.5 moles * (2 moles NH3 / 3 moles H2) = 1 mole of NH3.

Can the number of moles of a substance be found by looking at a balanced equation?
yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O
How many moles in a teaspoon of chalk?
The molecular weight(M) of chalk(CaCO3) = (40+12+48)g/mol =100g/mol and teaspoon (m)= 4.93g We know, n=m/M So, n= (4.93/100) mol = .0493 mol To find out number of molecules we use, N= n x NA equation. N= .0493 mol x 6.02 x 1023 molecules/mol =2.968 x 1022 molecules Therefore, there are 2.968 x 1022 molecules in a teaspoon of chalk.
What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?
The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".
How do you solve this question?
Titration equation can be solved by following the steps below: 1. write a well balanced equation. 2. Calculate number of moles of standard solution that is in the solution. 3. User molar relationship to convert moles of standard solution to that of unknown solution. 4. Find the number of moles of unknown solution.
What is the mole ratio that can convert from moles of a to moles of b?
The mole ratio to convert from moles of a to moles of b is determined by the coefficients of a and b in the balanced chemical equation. For example, if the balanced equation is 2A + 3B -> 4C, the mole ratio would be 3 moles of B for every 2 moles of A.
