How many moles are in 3.4x10-7 grams of silicon dioxide?

Answer 1

11 grams of silicon Si equals 0,39 moles.

Answer 2

To find the number of moles, we need to convert the given mass in grams to moles. The molar mass of silicon dioxide (SiO2) is approximately 60 grams/mol. Number of moles = (3.4x10^-7 grams) / (60 grams/mol) = 5.7x10^-9 moles.

Answer 3

MgSiO3 is magnesium silicate and it has a molar mass of 100.4 g/mole.
177 g x 1 mol/100.4 g = 1.76 moles (to 3 significant figures)

Answer 4

The value in moles is 1,997.10e-9.

Answer 5
