How many formula units are in 5.1 grams of TiO2?

Answer 1

To determine the number of formula units in 5.1 grams of TiO2, we first need to calculate the molar mass of TiO2. Titanium (Ti) has a molar mass of approximately 47.87 g/mol, and oxygen (O) has a molar mass of around 16.00 g/mol. Adding these together gives a molar mass of TiO2 as 79.87 g/mol. Next, we use the formula: number of formula units = (mass given / molar mass) x Avogadro's number. Substituting the values, we get (5.1 g / 79.87 g/mol) x 6.022 x 10^23 = approximately 3.85 x 10^22 formula units of TiO2 in 5.1 grams.

Answer 2

You have to start with 5.1 and multiply it by 6.022 x 10^23 (AKA "The Number") then divide it by 236.381- the molar mass of TiO2- and you get 1.2992 or if you have to put it sig figs the answer is 1.3 x 10^22. :)

Answer 3

To find the number of formula units in 5.1 grams of TiO2, we first need to determine the molar mass of TiO2, which is 79.87 g/mol. Next, we calculate the number of moles of TiO2 in 5.1 grams using the formula moles = mass/molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to convert moles to formula units: formula units = moles x Avogadro's number.

Answer 4

3.8x10^22 :)
