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.
125 grams Ca / (40.1 grams) = 3.12 moles Ca

Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
How many grams are in 1.25 moles of calcium carbonate?
To answer this we must first find the molar mass of calcium carbonate. CaCO3Ca= 40.08gC=12.01gO= 16.00g (we have three oxygens so 16.00x3 is 48.00g)40.08+12.01+48.00= 100.09 gNow that we have the molar mass we can find how many grams there are:1.25 moles CaCo3 x (100.09 g CaCO3/ 1 mole CaCO3)= 125.11 grams CaCO3Therefore we'd have about 125 grams of CaCO3
How do you find out the mass of 1.25 moles of calcium carbonate?
This question is solved with the help of mole concept . 1 mole of anhydrous calcium carbonate weighs 40+12+48=100 gm . 1.25 mole of similar anhydrous calcium carbonate will be 100* 1.25 = 125 gm
What is the molarity of a solution that contains 125 g NaCl dissolved in 4.00 L of solution?
The Molarity of the solution is .901
How many moles are in 125.00 grams of sodium sulfide?
There are at least three kinds of sodium sulfide, but assuming that the question refers to the most common one with the formula Na2S, its gram formula mass, the mass corresponding to molar mass for covalently bonded compounds, is 78.04. Therefore 125.00 constitutes 125.00/78.04 or 1.6017 "moles".

If you have 125 grams of zinc how many moles of zinc do you have?
To calculate the number of moles of zinc, use the formula: moles = mass (grams) / molar mass (grams/mol). The molar mass of zinc (Zn) is approximately 65.38 g/mol. Therefore, 125 grams of zinc is equal to 125 g / 65.38 g/mol, which is about 1.91 moles of zinc.
How many ounces of beef is 125 grams?
To convert grams to ounces, you can use the conversion factor that 1 ounce is approximately 28.35 grams. Therefore, to convert 125 grams to ounces, divide 125 by 28.35, which is about 4.41 ounces. So, 125 grams of beef is approximately 4.41 ounces.
How many grams of KCl are needed to prepare 125 mL of a 0.720 M KCl solution?
To calculate the amount of KCl needed, we first need to find the number of moles of KCl required using the formula: moles = Molarity x Volume (in L). Then, we convert moles to grams using the molar mass of KCl, which is 74.55 g/mol. Finally, we use the formula: grams = moles x molar mass to find that approximately 6.33 grams of KCl are needed to prepare 125 mL of a 0.720 M solution.
How many grams of carbon dioxide are needed to produce 125 grams of urea?
To produce 1 mole of urea, 1 mole of carbon dioxide is needed. The molar mass of urea is 60 grams/mol, and the molar mass of carbon dioxide is 44 grams/mol. Therefore, to produce 125 grams of urea, 125 grams/60 grams/mol = 2.08 moles of urea is needed. This means 2.08 moles of carbon dioxide is needed, which is 2.08 moles * 44 grams/mol = 91.52 grams of carbon dioxide needed.
How do you find out the mass of 1.25 moles of calcium carbonate?
This question is solved with the help of mole concept . 1 mole of anhydrous calcium carbonate weighs 40+12+48=100 gm . 1.25 mole of similar anhydrous calcium carbonate will be 100* 1.25 = 125 gm
How many kg are in 125 g?
1000 grams= 1 kilogram 125 grams= .125 kilo grams and instead of asking people online, next time DIY!!!!!!!!!!!!!
What is the ratio of 125 grams 1 kg?
To find the ratio of 125 grams to 1 kilogram, first convert 1 kilogram to grams. Since 1 kilogram equals 1000 grams, the ratio of 125 grams to 1000 grams is 125:1000. This can be simplified to 1:8 by dividing both numbers by 125.
What is 125 gof HSO in moles form?
No such thing as HSO in chemistry. If you're referring to H2SO4, which is sulfuric acid, then 125 grams of it would be: H2SO4 = 98g/mol; 98/1=125/x; solve for x to get about 1.28 moles.
How would one convert 125 lb to kilograms ( 1 oz 28 grams?
To convert 125 lb to kilograms, you would first convert pounds to ounces (125 lb * 16 oz/lb = 2000 oz) and then convert ounces to grams (2000 oz * 28 g/oz = 56000 g). Finally, convert grams to kilograms by dividing by 1000 (56000 g / 1000 = 56 kg). So, 125 lb is equal to 56 kilograms.
How many moles of mercury (II) oxide are needed to produce 125 grams of oxygen?
To find the moles of mercury (II) oxide (HgO) needed to produce 125 grams of oxygen (O2), we first calculate the moles of O2. The molar mass of O2 is approximately 32 g/mol, so 125 g of O2 corresponds to about 3.91 moles (125 g ÷ 32 g/mol). The decomposition of 2 moles of HgO produces 1 mole of O2, meaning we need 7.82 moles of HgO (3.91 moles O2 × 2) to produce that amount of oxygen. Thus, 7.82 moles of mercury (II) oxide are required.
