How many moles are 5 grams of calcium ? (Atomic mass of calcium = 40 u). Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium.

## How many moles are 5 grams of calcium CA 40u?

How many moles are 5 g of calcium? [ans=0.125 mole] Q. 6 What is the mass of 4 moles of aluminium atoms? (ans= 108 el Q.

## How many moles are in 5 grams of calcium?

Molar mass of Calcium=40.078 g/mol. So numbers of moles =5.00/40.078=0.125 mol.

## How many moles are in 10 g of calcium at mass of CA 40u?

∴ The Number of Moles in 10 g of Calcium (Ca)

Hence, There are 0.25 Moles in 10 g of Calcium . . .

## What is the mass of 4 moles of calcium atoms atomic mass of calcium 40u?

Explanation: Given:atomic mass of calcium is 40u.No. of moles =given weight/molecular weightNo. of Cu moles=0.4/40=1/00=0.01molesWe know that 1 mole of any substance contains 6.023 x 10²³ atoms/ molecules/ions1mole of Cu contains=6.023 x 10²³ atoms of Cu0.

## What is the mass of 5 moles of calcium?

The symbol for calcium is Ca, and the symbol for grams is g. Therefore, 5 moles of calcium to grams is the same as 5 moles of Ca to grams, 5 moles of calcium to g, and 5 moles of Ca to g. Furthermore, the atomic mass of calcium is 40.08. That means that one mole of calcium weighs 40.08 grams (40.08 g/mol).

## How many moles are in calcium?

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How many moles of caco3 are present in 250gm of caco3?

=250⋅g100.09⋅g⋅mol−1formula mass of calcium carbonate=2.50⋅mol … …and thus there are 2.50⋅mol of calcium atoms present, 2.50⋅mol of carbon atoms present, and 7.50⋅mol of oxygen atoms present; are you clear as to how we got these numbers?

## How many moles are in 10 grams calcium?

so,10g of ca contains 0.5 mol.

## How many moles are there in 8 grams of calcium?

Thus,there are 0.2 mole in 8 g of calcium.

## 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.
