How many moles are in 3.4 x 10-7 grams of Silicon dioxide, SiO2?

Varvara68 [4.7K]

Answer:

Number of moles = 0.057 × 10⁻⁷ mol

Explanation:

Given data:

Mass of SiO₂ = 3.4 × 10⁻⁷ g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of SiO₂ = 60 g/mol

by putting values,

Number of moles = 3.4 × 10⁻⁷ g / 60 g/mol

Number of moles = 0.057 × 10⁻⁷ mol
