Question

1.10 Which of the following samples will have the same
volume under similar conditions of temperature and
pressure ?
a.
64 g SO2
b. 4 g He
C.
16 g 02
d. 6.023x1023 molecules of N2
(1) both a &b
(2) a, b, d but not c
(3) b, c, d but not a (4) a, b, c, d
​

Answer 1

Answer:

Answer is (3)

Explanation:

A)Molecular weight of SO2=32

Given 64g of SO2

So number of moles=Mass/GMW=64/32=2 moles

B)Molecular weight of He=4

Givem mass=4g

Number of moles=1

C)Molecular weight of O2=16

Given weight=16

Number of moles=1

D)1 mole of N2 contains 6.023*10^23 molecules

so number of moles=1
