Question

Calculate
the mass of 5 moles of
Ca(co3) in grams.​

Answer 1

Answer:

hey

Explanation:

Metals when react with HCl to form salt and hydrogen gas but when they react with concentrated HNO3 to form water instead if hydrogen gas. Why? give two example of metal when react with Dil HNO3 to form salt and hydrogen gas.

Answer 2

The Gram Molecular weight of Calcium carbonate (CaCO₃) is 40 + 12 + 48 = 100 grams

It means that 1 mole of CaCO₃ weighs 100 grams

So, 5 moles of CaCO₃ weighs 5 x 100 = 500 grams
