## What is the mass of 0.2 moles of calcium carbonate?

Hence, the mass of 0.2 moles of CaCo3 is **20 g**.

## What is the mass of 0.5 moles of calcium?

0.5 moles of calcium element have a mass of **20g**.

## What is the mass of 0.25 moles of CaCO3?

They will be obtained from 0.25 moles of calcium carbonate. 0.25 moles of calcium carbonate (molecular weight 100 g/mole) corresponds to **25 g**.

## How many mole S of calcium carbonate caco3 is represented by 50 grams of the compound?

100g Caco3=1mole.. , 50g of caco3=1÷100×50=**0.5 mol**..

## How many grams are in 0.50 moles of calcium?

Furthermore, the atomic mass of calcium is 40.08. That means that one mole of calcium weighs 40.08 grams (40.08 g/mol). Based on that information, to convert 0.5 moles of calcium to grams, we multiply 0.5 moles of calcium by 40.08.

## What is the mass of 4 moles of calcium atoms?

Answer: since the atomic weight of calcium is 40 therefore 1 mole will have 40 grams weight. hence 4 moles will have **160grams weight**. hope this helps you.

## How many moles are in 50g of CA?

Calculate the number of moles present in the following : (a) 50 g of calcium chloride. =**0.450 moles**.

## How many moles of caco3 are there in 25g of caco3?

In order to calculate the number of moles in 25 g of calcium carbonate following formula will be used. weight of calcium carbonate given= 25 g. = **0.25 moles**. thus number of moles in 25 g of calcium carbonate is 0.25.

## How many moles are there in 100g of CaCO3?

Solution — Molar mass (Molecular mass in gram) of CaCO3 = 40+12+3×16 = 100 g No. of moles of CaCO3 = No. of molecules/Avogadro constant = 6.022 × 1023/ 6.022 × 1023 = **1 mole** Mass of CaCO3 = No. of moles × molar mass = 1 × 100 g = 100 g.

## What is the mass of 0.2 mole of h2?

Weight of 0.2 mole H_{2} gas = 2(Mol. Mass) x 0.2 = **0.4 g**.

## How many moles are there in 40g of CaCO3?

Calcium carbonate is CaCO3 so there is (in **one mole**) 40g of calcium because there would be one mole of that, 12g of carbon because there would be one mole of that, and 48g of oxygen because there are three moles of that.
