A container initially holds 5.67 x 10^-2 mol of propane and has a volume of V1. The volume of the container was increased by add
Brut [27]

Answer:

Initial volume of the container (V1) = 1.27 L (Approx)

Explanation:

Given:

Number of mol (n1) = 5.67 x 10⁻²

Number of mol (n2) = (5.67 +2.95) x 10⁻² = 8.62 x 10⁻²

New volume (V2) = 1.93 L

Find:

Initial volume of the container (V1)

Computation:

Using Avogadro's law

V1 / n1 = V2 / n2

V1 / 5.67 x 10⁻² = 1.93 / 8.62 x 10⁻²

V1 = 10.9431 / 8.62

Initial volume of the container (V1) = 1.2695

Initial volume of the container (V1) = 1.27 L (Approx)

How many moles is 0.025 g of NaCO3? (Show Your Work)
poizon [28]

mol of Na2CO3 = 2.36 x 10⁻⁴

<h3>Further explanation</h3>

Given

Mass : 0.025 g of Na2CO3

Required

moles

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass  :

mol = mass : molar mass

mass = mol x molar mass

Input the value :

mol = mass : MW Na2CO3

mol = 0.025 g : 106 g/mol

mol = 2.36 x 10⁻⁴
