The molar mass of silicon is approximately 28.09 grams per mole. To find the weight of 5.5 moles of silicon, you can multiply the number of moles by the molar mass: (5.5 , \text{moles} \times 28.09 , \text{g/mol} \approx 154.49 , \text{grams}). Therefore, the weight of 5.5 moles of silicon is approximately 154.49 grams.

How many grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?
To find the amount of chlorine needed to combine with silicon to form silicon tetrachloride, first calculate the molar masses of silicon and chlorine (28.09 g/mol and 35.45 g/mol, respectively). As silicon tetrachloride has a 1:4 ratio of silicon to chlorine, this means 1 mole of silicon (28.09 g) will react with 4 moles of chlorine (4 * 35.45 g) to form silicon tetrachloride. Therefore, to find the grams of chlorine needed to combine with 24.4 grams of silicon, calculate (24.4 g Si / 28.09 g Si) * (4 moles Cl * 35.45 g Cl).
How many atoms are in four moles of silicon?
A mole of silicon (or any other element, for that matter) contains 6.02 x 1023 atoms. A mole of any compound contains that same amount of molecules. That big number is Avogadro's number, and more can be found by using the links below.

One mole of silicon (Si) has a mass of 28.086 g and one mole of carbon has a mass of 12.011 g. What is the mass of one mole of silicon carbide (SiC)?
The molecular formula of silicon carbide is SiC. To find the molar mass of SiC, add the molar mass of silicon (28.086 g) and carbon (12.011 g) together: 28.086 + 12.011 = 40.097 g/mol. Therefore, the molar mass of one mole of silicon carbide (SiC) is approximately 40.097 g.
How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
What is the weight of one mole of sulfur?
The molecular weight of 1 mole of sulfur is 32 amu or grams.
How many moles of silicon do you have if you have 6.02 x 1024 atoms?
A mole of the element silicon is generally considered to have Avogadro's Number of atoms, since there is no particular small number of silicon atoms that is known to have distinct and persisting chemical bonds different from those of any other part of a sample of silicon. The number shown in the question is about 10 times Avogadro's Number and therefore contains ten moles.
What is the atomic mass or weight of Silicon?
Atomic weight 28.086
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.
What is the atomic weight in grams per mole of the element?
The atomic weight in grams per mole of an element is the average mass of one mole of atoms of that element, measured in grams.
In a sample of silicon dioxide the mass of oxygen is 60g. what is the mass of silicon present?
To determine the mass of silicon present in silicon dioxide, we need to consider the chemical formula, which is SiO2. This means that for every 1 mole of SiO2, there is 1 mole of silicon and 2 moles of oxygen. Since the molar mass of oxygen is 16 g/mol, the mass of oxygen in 60 g of SiO2 corresponds to 60/16 = 3.75 moles of oxygen. Therefore, the mass of silicon will be 28 g/mol (molar mass of silicon) * 1 = 28 g.
How many grams of oxygen are in 10.00x1028 molecules of silicon dioxide?
10.00 X 10^28 = 1.0 X 1^29 ( always use scientific notation in chemistry ) 1.0 X 10^29 molecules silicon dioxide (1 mole SiO2/6.022 X 10^23)(2 mole O/1 mole SiO2)(16.0 grams/ 1 mole O) = 5.3 X 10^6 grams of oxygen
What is the chemical name for SiS2?
