How many moles of calcium is 126g of ca?
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
How many moles of calcium are there in 77.4 grams of Ca?
To find the number of moles, you need to divide the given mass of calcium by its molar mass. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Number of moles = 77.4 g / 40.08 g/mol ≈ 1.93 moles.
How many grams of ca(no3) are needed to make a 250 ml of 0.50M solution?
To calculate the amount of Ca(NO3)2 needed for a 0.50M solution: Find the molar mass of Ca(NO3)2 = 164.09 g/mol. Calculate the number of moles needed: 0.50 moles/L x 0.250 L = 0.125 moles. Convert moles to grams: 0.125 moles x 164.09 g/mol ≈ 20.51 grams of Ca(NO3)2 are needed.
Empirical formula for a compound that contains 32.2 percent Ca and 67.8 percent N by mass?
Assume the compound has a molar mass of 100 grams, from the information given, 32.2 grams is Calcium and 67.8 grams is Nitrogen.You then find the moles of each, which would be moles of Ca and moles of N.Dividing the two moles gives you the mole fraction: which we approximate to 6. This means that for every 1 mole of Ca, there are 6 moles of N, thus the answer is
How many grams are there in .761 moles of Ca?

How many grams are in .07 moles of Ca?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Calcium's atomic mass is 40.08 grams.
How many moles are in forty grams of calcium?
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.40.0 grams Ca / (40.08 grams) = .998 moles Ca
How many moles of calcium is 126g of ca?

What is the mass of 3.61 moles of Ca?
Well, darling, the molar mass of calcium (Ca) is approximately 40.08 g/mol. So, if you have 3.61 moles of Ca, you just need to multiply the molar mass by the number of moles to find the mass. In this case, 3.61 moles of Ca would have a mass of around 144.88 grams. Hope that clears things up for you, sugar!
Calculate the mass in grams of 2.5 moles in calcium carbonate?
For this you need the atomic (molecular) mass of CaCO3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CaCO3= 100.1 grams2.50 moles CaCO3 × (100.1 grams) = 250.25 grams CaCO3
How many grams are in 0.658 mole of calcium phosphate?
To find the mass of calcium phosphate (Ca₃(PO₄)₂) in grams for 0.658 moles, first calculate its molar mass. The molar mass of calcium phosphate is approximately 310.18 g/mol. Multiply the number of moles by the molar mass: 0.658 moles × 310.18 g/mol ≈ 204.4 grams. Thus, there are about 204.4 grams of calcium phosphate in 0.658 moles.
How many moles of calcium are in 5000 grams of calcium?
To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.
How many moles of calcium are there in 77.4 grams of Ca?
To find the number of moles, you need to divide the given mass of calcium by its molar mass. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Number of moles = 77.4 g / 40.08 g/mol ≈ 1.93 moles.
How many moles of calcium ca atoms are in 98.5 g of ca?
To determine the number of moles of calcium atoms in 98.5 g of Ca, you need to first calculate the molar mass of Ca (40.08 g/mol). Then, divide the given mass by the molar mass to get the number of moles. So, 98.5 g of Ca is equal to 98.5 g / 40.08 g/mol ≈ 2.46 moles of Ca atoms.
How many moles are there in 23 grams of sodium?
First of all, we should know what a mole and molar mass of an element means. Then answering this question would be easy. Mole is a number( like pi, 1, 2, etc.). It is approximately 6.0225 *1023 . 1 mole of anything is same as the number of atoms in 12 grams of Carbon C12 sample. The mass of mole of an element/compound is called it's molar mass expressed in grams. The molar mass of a monoatomic element is equal to it's mass number. So, we know Ca's mass number = 40. that means 1 mole of Ca weighs 40 grams. =>1/40 mole of Ca weighs 1 gram. =>(1/40)*23 moles of Ca weighs 23.0 gram. =>0.575 moles of Ca weighs 23.0 gram. So there are 0.575 moles of Ca atoms in 23.0g of Ca
How many moles of atoms are in 500.00 mg of calcium?
Calcium hydroxide (Ca(OH)2) has a molar mass of 74g/mol. To find the number of moles in 0.5000g of calcium hydroxide, you divide the 0.5000gCa(OH)2 by 74gCa(OH)2. The answer is 0.006757mol Ca(OH)2 to the nearest significant figure.
