How many atoms are present in 0.0350 mol of barium phosphate
lesya692 [45]
There are 3 Barium, 2 Phosphorus and 8 Oxygen in Barium Phosphate (Ba3(PO4)2, making 13 units. Multiply 0.0350 mol given by 13 and then you get 0.455 mol. Since they want atoms, multiply 0.455 by Avogadro's number (0.455 x 6.023 x 1023) and you get 2.74 atoms of barium phosphate.

What is the mass of 0.5 moles of carbon tetrafluoride, CF4?
VashaNatasha [74]

Answer:

44 g

Explanation:

The formula for the number of moles (n) is equal to n=\frac{mass}{molecular weight} .

Since we need to find the mass, we derive it from the formula of the number of moles and we get that mass = n x molecular weight .

The molecular weight of CF_{4} = 12 g/mol (from the carbon) + 19x4 g/mol (from the 4 fluorine atoms)= 88 g/mol

We plug in the numbers in the derived formula for the mass and we get :

mass = n x molecular weight = 0.5 mol x 88 g/mol = 44 g
