Question

The relative molecular mass of sulphur dioxide is 64.Which statment is not true
a.)one mole of sulphur dioxide weighs 64g
b)one mole of sulphur dioxide occupies a volume of 22.4 dm^3 at stp
c)one mole of sulphur dioxide contains 6.02x10^23 molecules of sulphur dioxide
d)one mole of sulphur dioxide contains 64x6.02x10^23 molecules

2.)


Every molecule of the compound benzene contains 6 carbon atoms and 6 hydrogen atoms which statment is incorrect?
a)the molecular formula is C6H6
b)The emperical formula of benzene is CH
c)Benzene is polyatomic
d)each benzene molecule weighs 78 amu
e)the relative molecular mass of ethanoic acid is 60

Answer 1

Molecular mass is in grams per 1 mole. So, for sulfur dioxide, 1 mol weighs 64 grams.

Answer 2

lol ur wrong @JoannaBlackwelder

Answer 3

How so?

Answer 4

1 mole of any substance = molar mass of that substance :)

Answer 5

they have asked Which statment is not true ?

Answer 6

is it e that is not true

Answer 7

i mean d

Answer 8

I was not answering the question directly, lol. I was giving information (true statements) about the content of the question.

lol i didnt find that as a hint :)

Answer 13

Ok...@csmith0355 , do you have ideas for the answer to the second question?

Answer 14

i would say B

Answer 15

No, empirical formulas are the smallest whole number ratio of he atoms in a compound. Since the compound is C6H6, the empirical formula is CH.
