How many atoms make up 3.29 g of silicon?
To determine the number of silicon atoms in 3.29 g, you first need to calculate the number of moles of silicon using its molar mass (28.0855 g/mol). Then, use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
How many atoms are in 15.6 g of silicon?
To find the number of atoms in 15.6 g of silicon, you would first calculate the moles of silicon using its molar mass (28.09 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. The final calculation would yield the number of atoms in 15.6 g of silicon.
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.
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.
What is the mass of 42.6 mol of Si?
Well, isn't that a happy little question! To find the mass of 42.6 moles of silicon, you'll need to multiply the number of moles by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 grams per mole, so when you multiply that by 42.6 moles, you get a mass of about 1197.6 grams. Just like painting a beautiful landscape, it's all about following the right steps with a touch of joy and curiosity!
How many moles are present in gram's of silicon Si?
1 g silicon is equal to 0,0356 moles.

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 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?
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 are in 3.4x10-7 grams of silicon dioxide?
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.
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 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).
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.
