Question

Arrange the following in order of their increasing mass in grams:
One atom of silver
One gram atom of nitrogen
One mile of calcium
One mole of oxygen molecules
10^23 atoms of carbon
One gram of iron

Answer 1

Answer:

1)mole=0.1

weight=mole x molar weight=0.1 x 107.87=10.787g

2) weight of H2SO4=0.1 x 98=9.8 g

3) mole =no of molecule/6.023 x 10^23

=10^23/6.023 x 10^23=1/6.023

weight of CO2= mole x molar weight

=1/6.023 x 44=7.3 g (approx)

4) weight of carbon=1g

5) mole =1/6.023

weight =mole x molar weight

=1/6.023 x 40=6.67 g (approx)

now increasing order of their masses:-

(4) < (5) < (3) < (2) <(1)

Explanation:

Answer 2

Answer:

1) Atomic mass of Silver =108g

2) Atomic mass of Nitrogen = 14g

3) One mole Calcium=Atomic mass of calcium =12g

4) One mole of oxygen molecules=O2=16x2=32g

5) 10^23 atoms of carbon=12/6.02= 2(approx)

6) One gram of iron =56g

order: 5,3,2,4,6,1
