Question

the weight of 0.01 mole of Na2CO3 is

Answer 1

Answer:

molar weight of

Na is 23, C is 12, and O is 16

molar weight of Na

2

CO

3

is 106gm

Now apply a very simple formula

moles =

molarmass

weight

0.1=

106

weight

Weight=10.6g

finally, we will get weight is 10.6 gm

so the answer is 10.6 g

Answer 2

ANSWER

Mole=

Molecular weight(M.W)

weight(w)

w=Mole×M.W

=0.1×106 (∵M.W of Na

2

CO

3

=106)

w=10.6 gm
