How much sodium is required to burn 1.2 g of sodium?

1.The volume is determined by the formula:

V = Vn n, where Vn is the molar volume of gas, equal to 22.4 l / mol, and n is the amount of substance.

2. To find the volume of sodium, you need to calculate its amount of substance by the formula:

n = m: M, where M is molar mass.

M (Na) = 23 g / mol.

n = 1.2 g: 23 g / mol = 0.05 mol.

3. Calculate the volume of sodium:

V (Na) = 0.05 mol x 22.4 L / mol = 1.12 L / mol.

Answer: V (Na) = 1.12 L / mol.
