Calculating the mass of 3.50 moles of silicon dioxide

Understanding the problem

We are given the number of moles of silicon dioxide and we need to calculate the mass of the compound. This problem involves using the molar mass of SiO2 to convert moles to grams.

Solution

First, we need to determine the molar mass of silicon dioxide (SiO2).

Molar mass of SiO2 = 60.09 g/mol

Next, we can use the formula:

Mass (g) = Number of moles x Molar mass

Plugging in the values:

3.50 mol x 60.09 g/mol = 210. g
