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 of calcium are in 5000 grams of calcium?
5000 grams calcium (1 mole Ca/40.08 grams) = 124.75 moles Calcium
How many grams is contained in .27 moles of calcium?
(2.7 mol Ca / 1) * (40.078 g Ca / 1 mol Ca) = 108.21 g Ca. After significant figures, the answer is 110 g Ca.
How many moles of ions are in 2 moles of CaOH2?
2 moles of Ca and 4 moles of OH
How many moles of calcium are in 425 g calcium (Ca)?
425 g calcium (Ca) is equal to 10,604 moles.
How many moles are in 978 g Ca?
978 g calcium contain 24,4 moles.
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 ca would be in 3.8G?
3.8 grams calcium (1 mole Ca/40.08 grams) = 0.09 moles calcium ==============
How many grams are there in .761 moles of Ca?
For this you need the atomic mass of Ca. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. Ca= 40.1 grams.761 moles Ca × (40.1 grams) = 30.5 grams Ca
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 are in 5000 grams of calcium?
5000 grams calcium (1 mole Ca/40.08 grams) = 124.75 moles Calcium
How many grams is contained in .27 moles of calcium?
(2.7 mol Ca / 1) * (40.078 g Ca / 1 mol Ca) = 108.21 g Ca. After significant figures, the answer is 110 g Ca.
How many moles of calcium are there in 77.4 grams of Ca?
77.4 gCa x 1 Mole Ca/40.08 gCa = 1.931 mol Ca
How many grams of CaOH2 are needed to prepare 300.0 mL of a 0.115 M solution?
Molarity = moles of solute/Liters of solution ( 300.0 ml = 0.300 liters ) ( Ca(OH)2 is correct formulation ) 0.115 M Ca(OH)2 = moles Ca(OH)2/0.300 Liters = 0.0345 moles Ca(OH)2 (74.096 grams/1 mole Ca(OH)2) = 2.56 grams of Ca(OH)2 needed
How many moles are in 12.2 grams of calcium?
12.2 g Ca/ 40.08 g/mol = .304 mol
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 moles of calcium ca atoms are in 98.5 g of ca?
The atomic mass of calcium, Ca is 40.1. First we calculate the amount in moles of calcium in a 98.5g pure sample.Amount of Ca = 98.5/40.1 = 2.46mol So there are 2.46 moles of Ca (or Ca atoms).
How many moles of Ca are there in 0.18moles of Ca F2?
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
