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 grams of sugar in it?

A. 1.5 x 10^26 particles

B. 6.02 x 10^23 particles

C. 4.4 x 10^23 particles

D. 1.8 x 10^21 particles

Sagot :

Number of particles inside a sugar bowl = 4.4 x 10²³

Further explanation

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 :

[tex]\tt mol=\dfrac{mass}{molar~mass}[/tex]

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
