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.
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)

How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
How many moles in 28.1 grams of silicon?
To determine the number of moles in 28.1 grams of silicon, you need to divide the given mass by the molar mass of silicon. The molar mass of silicon is 28.0855 g/mol. So, 28.1 grams of silicon is equal to 1 mole.
How do you calculate the number of moles in 2.61 grams of silicon?
To calculate the number of moles in 2.61 grams of silicon, divide the given mass by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 g/mol. So, 2.61 g ÷ 28.0855 g/mol ≈ 0.093 moles of silicon.
How many moles does 11 g of silicon contain?
Ah, let's paint a happy little picture with some silicon! To find out how many moles are in 11 grams of silicon, we need to use the molar mass of silicon, which is about 28.09 grams per mole. So, by dividing 11 grams by the molar mass, we find there are approximately 0.39 moles of silicon in 11 grams. Just remember, in the world of chemistry, every little bit counts!
How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?
To find the moles of carbon, first calculate the moles of carbon dioxide using its molar mass. Then, from the moles of carbon dioxide, determine the moles of carbon as there is one carbon atom in each molecule of carbon dioxide. Calculate the moles of water and subtract from the initial moles of carbon dioxide to account for the moles of hydrogen and oxygen.
How many moles are there in 5 grams of silicon dioxide?
To determine the number of moles in 5 grams of silicon dioxide (SiO2), you first need to calculate the molar mass of SiO2. The molar mass of SiO2 is 60.08 g/mol. Then, use the formula Moles = Mass / Molar mass to find that there are approximately 0.083 moles in 5 grams of SiO2.
How many moles of carbon dioxide are there in 19 grams of carbon dioxide?

What is the mass of 0.1 moles of silicon?
The molar mass of silicon is approximately 28.0855 g/mol. Therefore, 0.1 moles of silicon would have a mass of 2.81 grams.
How many grams of oxygen are in 10.00x1028 molecules of silicon dioxide?
To find the number of moles of silicon dioxide in 10.00x10^28 molecules, divide this number by Avogadro's number (6.022x10^23). Then, multiply the result by the molar mass of silicon dioxide (60.08 g/mol) to find the mass of silicon dioxide. Since silicon dioxide consists of 2 oxygen atoms, you can calculate the mass of oxygen by multiplying the mass of silicon dioxide by the ratio of oxygen's molar mass to the total molar mass of silicon dioxide.

How many grams of carbon dioxide are needed to produce 125 grams of urea?
To produce 1 mole of urea, 1 mole of carbon dioxide is needed. The molar mass of urea is 60 grams/mol, and the molar mass of carbon dioxide is 44 grams/mol. Therefore, to produce 125 grams of urea, 125 grams/60 grams/mol = 2.08 moles of urea is needed. This means 2.08 moles of carbon dioxide is needed, which is 2.08 moles * 44 grams/mol = 91.52 grams of carbon dioxide needed.
How many grams of oxygen will be required to produce 25 moles of sulfur dioxide how many grams of oxygen will be required to produce 25 moles of sulfur dioxide?
800 g oxygen are needed.
How many atoms of oxygen are in 0.100 moles of silicon dioxide?
There are 2 atoms of oxygen in each molecule of silicon dioxide (SiO2). Therefore, in 0.100 moles of SiO2, there would be 0.100 moles * 2 atoms = 0.200 moles of oxygen atoms. Finally, since 1 mole of any element contains 6.022 x 10^23 atoms, there are (0.200 moles) * (6.022 x 10^23 atoms/mole) = 1.204 x 10^23 atoms of oxygen in 0.100 moles of silicon dioxide.
