The sugar in your kitchen has a molar mass of 342.3 g/mol. How many particles are present inside a sugar bowl if there are 250 g
Anastaziya [24]

Number of particles inside a sugar bowl = 4.4 x 10²³

<h3>Further explanation</h3>

Given

The molar mass of sugar = 342.3 g/mol

mass of sugar = 250 g

Required

Number of particles

Solution

1 mol = 6.02 x 10²³ particles

mol of sugar :

\tt mol=\dfrac{mass}{molar~mass}

mol = 250 g : 342.3 g/mol = 0.73 mol

Number of particles :

N = n x No

N = 0.73 x 6.02 x 10²³

N = 4.39 x 10²³ ≈ 4.4 x 10²³
