For this you need the Atomic Mass of Si. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.
2.61 grams Si / (28.1 grams) = .0963 moles Si

How many moles in 28.1 grams of silicon?
6.02
How many moles are in 3.4x10-7 grams of silicon dioxide?
11 grams of silicon Si equals 0,39 moles.
How you calculate the mass of 1.5 moles of oxygen molecule?
Multiply the molar mass value ( 32.0 grams per mole O2) by the number of moles (1.5 mole) to get its mass (48.0 grams for 1.5 mole O2)
How many moles does 11 g of silicon contain?
Approximately 0.3915984336 mol ... or simply, 0.39 moltake the number 11 from 11g, and divide it by the molar mass of Si on the periodic table, which is the number with usually a decimal. This is how to get moles from grams for any element.
Calculate the number of atoms in 0.543 mol of silicon?
The number of molecules in a mole is known as "Avogadro's Number" and is about 6.002 times ten to the twenty-third power. Therefore, the number of moles is 0.543 X 6.022 = 3.27 times ten to the twenty-third power. (This answer will be the same for moles of any substance.) Silicon is generally regarded as having only one atom per molecule, so that the number of atoms will be the same as the number of moles. Under certain conditions, however, silicon may occur as polyatomic molecules, and in such an instance the answer would be different.
How many moles are in 1.5 grams of iron?
To calculate the number of moles from grams, you must divide by the substance's molar mass
Can you calculate the number of moles of magnesium used grams permol?
Yes
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
How many moles in 28.1 grams of silicon?
6.02
How do you calculate the gram molecular weight if you have 3.9176 grams and 0.122400 moles?
See the Related Questions to the left of this answer:"How do you convert from grams to moles and also from moles to grams?"
What is the mass of 0.1 moles of silicon?
On the periodic table, sililcon (Si) has an atomic mass of about 28 grams per mole. You have 0.1 moles, so just move the decimal once to the left to get 2.8 grams of silicon.
Calculate the number of moles in 0.135 grams of HNO3. Choose the correct answer.?

How do you calculate the number of moles in 0.998 grams of CH4O?
For this you need the atomic (molecular) mass of CH4O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CH4O=32.0 grams.998 grams CH4O / (32.0 grams) =.0312 moles CH4O
How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
