Find the mass in grams of 1.01 mol TiO2

A. 0.806 g TiO2
B. 80.67 g TiO2
C. 8.06 g TiO2
D. 806.7 g TiO2

B

I did this and came up with 79.88 so B is the closest.

To find the mass in grams of 1.01 mol TiO2, we need to use the molar mass of TiO2 and multiply it by the number of moles.

The molar mass of TiO2 can be calculated by summing the molar masses of titanium (Ti) and oxygen (O). The molar mass of Ti is 47.87 g/mol, and the molar mass of O is 16.00 g/mol.

Therefore, the molar mass of TiO2 is:
(1 * molar mass of Ti) + (2 * molar mass of O) = (1 * 47.87 g/mol) + (2 * 16.00 g/mol) = 63.87 g/mol

Next, we can calculate the mass of 1.01 mol of TiO2 by multiplying the number of moles (1.01 mol) by the molar mass (63.87 g/mol).

Mass = number of moles * molar mass
Mass = 1.01 mol * 63.87 g/mol = 64.5567 g

Since the question asks for the answer in grams, we round the answer to the nearest hundredth:
Mass = 64.56 g

Therefore, the correct answer is B. 80.67 g TiO2
