## How many moles are in 5 grams?

Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

## How many moles of hydrogen are in 25 moles of water?

Answer. Answer: There are 2.77 moles of hydrogen in 25 g of water. Thus 1.39 moles of contains = of hydrogen. Thus there are 2.77 moles of hydrogen in 25 g of water.

## How many moles are in 20 grams of CA?

You can determine the number of moles of calcium chloride by first finding its molecular mass (Ca + 2x Cl, or 40.08 + 2x 35.45 = 110.98 g/mole) and then dividing the number of grams of CaCl2 by the molecular weight to get moles. answer choices . 20 grams Calcium to mol = 0.49903 mol. Leslie Storer.

## What is the mass of a mole of h2so4?

98.079 g/mol

## How do you calculate the number of moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## What is the formula mass of CaCO3?

100.0869 g/mol

## How many moles are present in 10 gram of calcium?

so,10g of ca contains 0.5 mol.
