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.
What does it mean to compare the density of an object to that of it in pieces?
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
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.
What is a way to calculate the mass of an object when you multiply its density by what?
You can calculate the mass of an object by multiplying its density by its volume. The formula to calculate mass is: mass = density x volume.
How do you calculate the relative density of a substance?
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
