Answer:

94.2 g/mol

Explanation:

Ideal Gases Law can useful to solve this

P . V = n . R . T

We need to make some conversions

740 Torr . 1 atm/ 760 Torr = 0.974 atm

100°C + 273 = 373K

Let's replace the values

0.974 atm . 1 L = n . 0.082 L.atm/ mol.K . 373K

n will determine the number of moles

(0.974 atm . 1 L) / (0.082 L.atm/ mol.K . 373K)

n = 0.032 moles

This amount is the weigh for 3 g of gas. How many grams does 1 mol weighs?

Molecular weight → g/mol → 3 g/0.032 moles = 94.2 g/mol

A Hydrocarbon C₄H₁₀ has a boiling point of 0, another hydrocarbon C₆H₁₄ has a boiling point of 69. What would you expect the boi
cupoosta [38]
If the trend is linear, that is boiling point increases by a constant amount for each additional saturated carbon, the boiling point of octane would be 69*2 because you are adding two saturated carbons. So the predicted boiling point is 138C, which is very close to the literature value

Ascorbic acid, or vitamin C (C6H8O6, molar mass = 176 g/mol), is a naturally occurring organic compound with antioxidant propert
ki77a [65]

Answer:

The mass of ascorbic acid in 2.87×10−4 mol are 50,5 mg

Explanation:

Molar mass = 176 g/mol

Moles . molar mass = grams.

2,87 x10*-4 m . 176 g/m = 50,5 x10*-3 grams

A human can take one sweet lime and half to cover the daily requirement of vitamin C. =)

What happens to the sugar from a sugar cube after it has dissolved in a cup of tea? (Molecule related)​
katovenus [111]

Answer: Sugar is very soluble in water. When you add the solid to the tea the key process is that the solid sugar dissolves in the warm liquid: the solid crystals are broken up into molecules which are every dispersed throughout the existing liquid.
