Question

number of ions in 50g of CaCO3

Answer 1

hey mate here is your answer

This should give 1 mol of CaCO3

There is only one Ca symbol in the chemical formula of CaCO3, which means one Ca^2+ ion per unit

There are 1 mol of units, and so there are 1 mol of Ca^2+ ions.

Multiply this by Avogadro's number and you have 6.022 x 10^23 ions of Ca2+.

hope this helps if it does pls mark as brainliest
