Answer 1

Answer:

Hello,

The solution to this problem is as follows.

Molar mass of bismuth carbonate is approximately 510 amu.

as we know,

formula for moles of a substance is

n= m (g)/ molar mass

therefore,

n= 330/510

n = 0.64 moles approx.

Hope it helps.

Stat blessed. :)

Answer 2

$\huge \boxed {\bf{ \green{ANSWER}}}$

We have, n = given mass/ molar mass.

=> n = 330/ 510

=> n = 0.743 moles.
