Question

what is the molar mass of sio2? 1 mol si = 28.09 g si 1 mol o = 16.00 g o 1 mol sio2 = ? g sio2 round your answer to two decimal places.

Explanation:

Step1: Identify elements and their quantity

$SiO_2$ has 1 Si and 2 O.

Step2: Calculate molar mass

The molar mass of $SiO_2$ is the sum of the molar - mass of Si and 2 times the molar - mass of O. So, $M = 28.09+2\times16.00$.

Step3: Perform calculation

$M=28.09 + 32.00=60.09$ g/mol.

Answer:

60.09
