To make silicon from sand, you would need to extract the silicon dioxide (SiO2) from the sand. The Atomic Mass of silicon dioxide is 60 grams/mole. Since the molar ratio of silicon to silicon dioxide is 1:1, you would need 45 grams of sand to obtain 15 grams of silicon (45 grams x 1 mol Si/60 g SiO2).

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 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 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.
How many atoms of silicon are contained in 8.5 x 10-5gm?
To calculate the number of silicon atoms in 8.5 x 10^-5 grams of silicon, you would first determine the molar mass of silicon (28.09 g/mol) and then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert grams to atoms. In this case, there are approximately 1.29 x 10^16 atoms of silicon in 8.5 x 10^-5 grams.
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 grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?

How many grams are needed to make a pint?
A US pint is 473 grams. - An Imperial pint is 568 grams
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 many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
How many grams of HCl are needed to make 21.5 grams of Na2SO4?
Sodium sulfate is not prepared from hydrogen chloride.
How many grams of HF are needed to make 0.50L of a 0.750 M solution?
The answer is 7,5g.
If 350 grams is needed for 10000 liters how many grams is needed for 3300 liters?
To solve this, we will figure out how many grams there are per litre. To do this, we will divide the overall amount of litres 350 grams goes into by 350, so we are dividing 350 by 10,000. This answer is 0.035. We will then multiply 0.035 (how many grams needed for one litre) by 3300, to get how many are needed for that many litres, which gives us 115.5 grams. 115.5 grams are needed for 3300 litres if 250 grams are needed for 10,000 litres.
