A sample of trifluoroacetic acid, C2HF3O2, contains 38.9 g of oxygen. Calculate the mass of the trifluoroacetic acid sample.

qwelly [4]

Answer:

138.6 g of C₂HF₃O₂ have 38.9 g of O

Explanation:

Trifluoroacetic acid → C₂HF₃O₂

Molar mass = Mass of C . 2 + Mass of H + Mass of F . 3 + Mass of O .2

Molar mass = 12 . 2 + 1 . 1 + 19 . 3 + 16 . 2 = 114 g /mol

1 mol of C₂HF₃O₂ has:

2 moles of C

1 mol of H

3 moles of F

2 moles of O

If we state the relation in mass by g we say:

114 g of C₂HF₃O₂ have 24g of C, 1 g of H, 57 g of F and 32 g of O

Let's make a rule of three:

32 g of O are contained in 114 g of C₂HF₃O₂

38.9 g of O may be contained in (38.9 . 114) / 32 = 138.6 g

Help this question is super hard!!

Answer:

They all can, but HCl would be the strongest conductors because they are strong acids/bases, meaning their ions dissociate at a faster rate in aqueous solution.

The density of air under ordinary conditions at 25°C is 1.19 g/L. How many kilograms of air are in a room that measures 10.0 ft

Lunna [17]

Answer: The mass of air present in the room is 37.068 kg

Explanation : Given,

Length of the room = 10.0 ft

Breadth of the room = 11.0 ft

Height of the room = 10.0 ft

To calculate the volume of the room by using the formula of volume of cuboid, we use the equation:

$V=lbh$
