What is the mass in grams of 0.330mol of calcium?
The mass is 0.330 mol Ca (40.08 g/mol) = 13.2 g Ca
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
What is the relative molecular mass of cano32?
The relative molecular mass of Ca(NO3)2, also known as calcium nitrate, can be calculated by adding the atomic masses of calcium (Ca), nitrogen (N), and three oxygen (O) atoms. The atomic masses are 40.08 g/mol for calcium, 14.01 g/mol for nitrogen, and 16.00 g/mol for oxygen. When you add these values together, the relative molecular mass of Ca(NO3)2 is 164.08 g/mol.
How many grams of phosphorus are in 500 grams of calcium phosphate?
The mass of phosphorus of any sample of calcium phosphate is the mass of the same multiplied by the percentage that phosphorus makes up of that sample. (mass of sample) x (mass of phosphorus/total mass) Therefore we must look at the chemical formula of the substance in question: Ca3(PO4)2. From this we can see that there are 2 phosphorus atoms attributing mass to the total molecule. The formula becomes: 500 g x 2x30.97 g/mol/310.17 g/mol = 99.8 g molar mass of phosphorus: 30.97 g/mol molar mass of calcium phosphate: 310.17 g/mol total mass: 500 g
How many moles are there in 180gm of water?
10 moles of water (molar mass 18.0 g/mol) in 180 g, because 180 /18.0 = 10
What is the mass in grams of 0.330 mol of calcium?
0.330 moles of calcium has a mass of 13.2 grams.
What is the molar mass of calcium acetate?
The molar mass of calcium acetate is approximately 142 g/mol.
What is the mass in grams of 0.330mol of calcium?
The mass is 0.330 mol Ca (40.08 g/mol) = 13.2 g Ca
What is the molecular mass of calcium?
40.078 g mol-1
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
How many moles are in 72g of Calcium Sulphate?
no of mol = mass/molar mass = 72/ (40+32+16x4) = 72/136 = 0.529 mol (3.s.f)
What is the relative molecular mass of cano32?
The relative molecular mass of Ca(NO3)2, also known as calcium nitrate, can be calculated by adding the atomic masses of calcium (Ca), nitrogen (N), and three oxygen (O) atoms. The atomic masses are 40.08 g/mol for calcium, 14.01 g/mol for nitrogen, and 16.00 g/mol for oxygen. When you add these values together, the relative molecular mass of Ca(NO3)2 is 164.08 g/mol.
What is the molar mass of calcium fluoride?
The formula is CaF2 so, its three atoms, one calcium and two fluorine atoms. add the molar mass of calcium(40 g/mol) and fluorine(19 g/mol X 2 because there are two atoms of fluorine) and you get 40+(19x2)=78 78 grams per mol
Calculate the number of moles in 54.0 grams of Calcium sulfate?
To calculate the number of moles in a sample, divide the mass of the sample by the molar mass of the compound. The molar mass of calcium sulfate is calculated by adding the atomic masses of calcium, sulfur, and four oxygen atoms: Ca = 40.08 g/mol S = 32.06 g/mol O = 16.00 g/mol Molar mass of calcium sulfate = (40.08 g/mol) + (32.06 g/mol) + (4 × 16.00 g/mol) = 136.14 g/mol Now we can calculate the number of moles in 54.0 grams of calcium sulfate: Number of moles = mass (g) / molar mass (g/mol) = 54.0 g / 136.14 g/mol = 0.397 moles (rounded to three decimal places)
What mass of calcium oxide will be obtained by heating 3 mol of caCO3?
3 mol CaCO3 will produce 3 mol CaO (and 3 mol CO2) on dry-heating. So 3 times the molar mass of CaO (56,1 g/mol) which is 168 g CaO
Why do you need 40 grams of calcium and 32 grams of sulfur to make 72 grams of calcium sulfide?
From the periodic table, calcium has a molar mass of 40.078g/mol and sulfur has a molar mass of 32.065g/mol. The formula for compound formed from calcium and sulfur, calcium sulfide is CaS. The molar mass of CaS is 72.143. So, if you round the numbers, 40g of Ca + 32g of S will produce 72g of CaS.
Which is the molar mass of the element Calcium?
To find the molar mass of Calcium, you have to multiply Calcium's atomic number by moles. The equation is: (6.022x10^23)x 40.08= 2.4136176x10^25
