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.
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 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.
If a compound containing chromium and silicon has 73.52 mass percent chromium what is its empirical formula?
To find the empirical formula, we need to determine the molar ratio of chromium to silicon. If 73.52% of the compound's mass is chromium, then the mass of silicon must be 100% - 73.52% = 26.48%. Next, we convert these percentages to moles, then divide by the smallest number of moles to get the simplest whole number ratio. The empirical formula is CrSi.
