Question

given 132 g of sio2, determine the number of moles of sio2. 1 mol sio2 = 60.09 g sio2 mol sio2 = 132 g sio2

Explanation:

Step1: Recall mole - mass formula

The formula to calculate the number of moles $n$ is $n=\frac{m}{M}$, where $m$ is the mass and $M$ is the molar mass. Here, $m = 132\ g$ (mass of $SiO_2$) and $M=60.09\ g/mol$ (molar mass of $SiO_2$).

Step2: Calculate the number of moles

$n=\frac{132\ g}{60.09\ g/mol}\approx 2.20\ mol$

Answer:

$2.20$
