Density can be calculated as the mass per a certain amount of volume. There are equations avaible to find the mass per unit cell as well as the volume of a unit cell such as d = (#particles/unit cell)(AW, g/mol)/(avagado's #)(edge legnth)^3

How many moles of MgO are produced from 11.2 L O2?

To determine the number of moles of MgO produced from 11.2 L of O2, you would first need to balance the chemical equation for the reaction involving MgO and O2. Then, using the ideal gas law and stoichiometry, you can calculate the moles of MgO produced.


How many moles are there in 160g of MgO?

To find the number of moles in 160g of MgO, you first need to calculate the molar mass of MgO which is 40.3 g/mol for Mg + 16.0 g/mol for O = 56.3 g/mol for MgO. Then, divide the given mass by the molar mass to get the number of moles: 160g / 56.3 g/mol = 2.84 moles of MgO.


How many moles are in 106 g of MgO?

To find the number of moles in 106 g of MgO, you first need to calculate the molar mass of MgO. The molar mass of MgO is 40.3 g/mol for Mg and 16.0 g/mol for O, so the total molar mass is 56.3 g/mol. To find the number of moles, divide the given mass by the molar mass: 106 g ÷ 56.3 g/mol ≈ 1.88 moles of MgO.


How many moles are present in 160g of MgO?

To determine the number of moles in 160g of MgO, you first need to calculate the molar mass of MgO, which is 40.3 g/mol for Mg and 16.0 g/mol for O. Adding these together gives a molar mass of 56.3 g/mol for MgO. Next, divide the given mass (160g) by the molar mass of MgO to find the number of moles present. So, 160g / 56.3 g/mol = 2.84 moles of MgO.

How many grams of MgO are produced when 40 grams of 02 react with Mg?

Using the balanced chemical equation: 2Mg + O2 -> 2MgO, we can see that 1 mol of O2 reacts with 2 moles of Mg to produce 2 moles of MgO. Calculate the moles of O2: 40g O2 / 32g/mol = 1.25 mol O2 From the equation, 1.25 mol O2 will produce 2.5 mol of MgO. Calculate the grams of MgO produced: 2.5 mol MgO * 40.3 g/mol = 100.75 grams MgO.
