what is the molar mass of sio2?\n1 mol si = 28.09 g si\n1 mol o = 16.00 g o\n1 mol sio2 = ? g sio2\nround your answer to two decimal places.
Answer
Answer:
60.09
Explanation:
Step1: Identify elements and amounts
1 Si and 2 O in SiO₂
Step2: Calculate molar - mass contribution of Si
The molar mass of Si is 28.09 g/mol.
Step3: Calculate molar - mass contribution of O
Since there are 2 O atoms, and molar mass of 1 O is 16.00 g/mol, contribution of O is 2×16.00 = 32.00 g/mol
Step4: Calculate molar mass of SiO₂
28.09+32.00 = 60.09 g/mol
