What is the mass percent of calcium in calcium suppleiment if 1.15g of CaCO3 is extracted from a 2.70g pill?
1.15 (g CaCO3) / 100.1 (g/mol CaCO3) =1.149*10-2 (mol Ca)1.149*10-2 (mol Ca) = 1.149*10-2 (mol Ca) * 40.08 (g/mol Ca) = 0.4604 g Ca0.4604 g Ca = 0.4604 g Ca / 2.70 g Supplement = 0.1705 * 100% = 17.1% Calcium (m%)
Does Ca and Ar have same mass numbers 40?
No, calcium (Ca) has a mass number of 40, while argon (Ar) has a mass number of 40 as well.
Mass of 3.400 mol Ca(OH)2?
The mass of 3,400 mol Ca(OH)2 is 251,9 g.
What is the mass number of Ca?
97% of the naturally occurring Calcium is isotope Ca-40, so massnumber 40. Other isotopes have massnumber 42 to 48
Mass number of Ca?
Calcium: ~Atomic weight: 40.078 ~Atomic #: 20 ~Density: 1.55 ~Alkali Earth Metal
What is the percent composition by mass of ca in caso4?
The molar mass of CaSO4 is 136.14 g/mol. The molar mass of Ca in CaSO4 is 40.08 g/mol. To find the percent composition of Ca by mass, divide the molar mass of Ca by the molar mass of CaSO4 and multiply by 100. This gives a percent composition of approximately 29.4%.
What is the mass of CaOH2 required to have 10g of calcium?
To calculate the mass of Ca(OH)2 required to have 10g of calcium, first determine the molar mass of Ca(OH)2 (74.1 g/mol). Since calcium accounts for 40% of the mass in Ca(OH)2, the mass of Ca in 10g Ca is 4g. Using the molar ratio (Ca:Ca(OH)2) to find the mass of Ca(OH)2 required, the answer is 60g.
What is the mass percent of calcium in calcium suppleiment if 1.15g of CaCO3 is extracted from a 2.70g pill?
1.15 (g CaCO3) / 100.1 (g/mol CaCO3) =1.149*10-2 (mol Ca)1.149*10-2 (mol Ca) = 1.149*10-2 (mol Ca) * 40.08 (g/mol Ca) = 0.4604 g Ca0.4604 g Ca = 0.4604 g Ca / 2.70 g Supplement = 0.1705 * 100% = 17.1% Calcium (m%)
Does Ca and Ar have same mass numbers 40?
No, calcium (Ca) has a mass number of 40, while argon (Ar) has a mass number of 40 as well.
Mass of 3.400 mol Ca(OH)2?
The mass of 3,400 mol Ca(OH)2 is 251,9 g.
What is the mass of of 2 moles of Ca(CH)2?
If you trhink to calcium hydroxide - Ca(OH)2 - this mass is 148,086 g.
What is the price of CA antivirus Plus?
The price of CA anti virus plus is $4.99 from the cnet website. The anti-virus software package can also be obtained online from other webistes for similar prices.
How do you say How is it going in french?
Ca man ca vas - That's how you say (How is it going) in french.
How much does 1 mole of Ca weigh?
The molar mass of calcium (Ca) is approximately 40.08 g/mol. Therefore, 1 mole of calcium would weigh around 40.08 grams.
What is the 1.0 molar mass of Ca?
The atomic weight of calcium is 40,078 g.
If 20.0 grams of Ca combines completely with 16.0 grams of S to form a compound what is the percent composition of Ca in the compound?
First, find the molar mass of Ca and S (40.08 g/mol for Ca and 32.06 g/mol for S). Next, calculate the moles of each element present (0.499 mol of Ca and 0.499 mol of S). Find the total mass of the compound (36.0 g) and calculate the percent composition of Ca (about 55.6%).
How many moles of calcium atoms are in 45.8 g of Ca?
To determine the number of moles of calcium atoms in 45.8 g of Ca, first find the molar mass of calcium (Ca) from the periodic table (40.08 g/mol). Then, divide the given mass by the molar mass of Ca to get the number of moles. In this case, 45.8 g of Ca is equal to 1.14 moles of Ca atoms.
